Introduction to Marsupial phyloSNPs

In this project, new genomic data from the Tasmanian devil (Sarcophilus harrisii), Tasmanian tiger (Thylacinus cynocephalus), and echidna (Tachyglossus aculeatus) are analyzed for significant changes at the protein coding level. The goal is to find single amino acid changes in one of these species at a highly invariant residue in a well-conserved exon in a gene with known or predictable tertiary structure. Such changes are thought to enrich for genetic changes with significant, adaptive biochemical or phenotypic consequences (1,2,3,4), in contrast to ordinary SNPs at positions of low conservation. Thus phyloSNPs are informative to the distinctive biology of the species carrying them and suggest a focus for subsequent experiment.

It is also of particular interest to determine the levels of variation within the Tasmanian devil population as a whole because the number of individuals have become low and possibly inbreed with adverse sequelae. For this it will be necessary to first determine sites of variation and then to genotype them across a large number of individuals.

Marsupial genomic and cDNA data to date has been quite limited compared to placental mammal. Yet as outgroup, metatheran animals provide important context to placentals and represent important context in understanding human protein evolution. The monotheres are inevitably limited by the paucity of extant species (basically platypus and echidna) and dim prospects for fossil DNA. Consequently echidna provides an important adjunct to the existing but incomplete platypus assembly. While extant birds and reptiles -- the preceding divergence node -- are abundant it must be remembered that a very considerable time elapsed (from 310 mry to 175 mry) prior to divergence of mammals with living representatives. This gap of 135 myr is comparable to the whole evolutionary record of theran mammals.


Assumed vertebrate phylogenetic tree

Marsupial relationships are taken from a 2009 paper establishing the mitochondrial genome sequences of the Tasmanian tiger (Thylacinus cynocephalus) and numbat (Myrmecobius fasciatus).

Phylo-sorting data

This tab-delimited table enables four different sort orders. These are needed because data can be missing from species in a manner that varies by gene, making data alignment difficult. Some alignment tools also lose input order, so that needs to be recovered. The ordering here flattens the phylogenetic tree by taking human (arbitrarily) at the top and resolving ambiguous situations (eg mouse, rat) by putting species with the best assemblies first.

The first two columns provide sort order number for the 44 species alignment at UCSC as phylogenetic and alphabetic order respectively. The third and fourth columns do this for a larger set of 53 species for which data is commonly available (notably in marsupials). The fifth column supplies the genSpp acronym and the sixth the Newick tree format syntax. These two columns by themselves will correctly draw the vertebrate phylogenetic tree in all online software without further editing. The final columns provide genus, species, and common name.

Candidate analysis

The first issue is error within the primary reads themselves; the second is whether the default 454 Newbler assembler correctly identified overelapping reads and put them together properly to give exon-spanning reads. Those issues are discussed elsewhere -- here it is assumed the reads at the PSU blast site are correct, so the entire focus is on subsequent bioinformatics. In some cases that results in retrospective identification and correction of errors, notably introduced frameshifts that are far too common.

After thorough evaluation, candidates are given a final heuristic score based on awarding 0,1,or 2 points for the following 13 critera:

  • the change is real: multiple reads support each of the two amino acid values
  • quality coverage: the entire exon can be recovered from multiple reads without manual frameshift correction
  • processed pseudogenes can be recognized by reads long enough at flanks to identify neighoring exons now adjacent (resp GT-AG splice donors)
  • non-processed pseudogenes can be distinguished by recovery of additional exons of the gene with expected levels of conservation
  • paralogs and internal repeats are readily distinguishable from the exon under stead
  • phylogenetic depth: multiple marsupials, monotremes, all placental branches, fish, chondrichthyes, possibly lamprey available
  • homoplasy: the reduced alphabet consists of a single amino acid with the exception of Sarcophilus
  • appropriate character of the change in amino acid properties
  • amenability to accurate rapid scoring in many individual animals
  • interpretability of structural significance of change within 3D structure or characterized domain
  • interpretability of functional role of overall gene and of region containing the amino acid change
  • previous relevant publications, animal kockout models, known human ortholog disease SNPs
  • plausible relevancy of the change to cancer or facial tumor

When scoring is finished, the dummy table below will be filled in with real data and genes will become sorted by highest overall score (or by preferred columns appropriate to specialized purposes).

Case of ERN2

KLPFTIPELVHASPCRSSDGVLYT

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in
tasmanian  devil (in this case, both individuals differ from Monodelphis by L->F), then differences between the two tasmanian devils
(here one individual has R at position 15, the other has H), and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. The sequences were assembled by Newbler (the official 454 assembler) which uses 
lower-case letters for less confident calls.

Pseudogene issues: ERN2 has not generated potentially confusing recent processed pseudogenes in mammals (lack of human, opossum or platypus genome Blat matches to ERN2 query). The variation observed here between individual tasmanian devils is implausibly an early stage in the loss of parent gene because of ERN2 functional essentiality; the exon cannot come from a decaying segmental duplication because coverage is high enough to also detect the main gene.

Paralog issues: The GeneSorter tool at UCSC shows a single significant full-length paralog in human, ERN1, also with 22 coding exons. The genes reside on different chromosomes but in regions with local homology of synteny. However this particular exon is a good match (3 differences out of 23), so there is potential for experimental difficulties in distinguishing them in short reads (including the following exon readily resolves them bioinformatically). In any event, at positions 15 and 20, ERN1 is identical at the amino acid level to ERN2. The gene duplication appears to have occured subsequent to amphioxus divergence earlier diverging metazoans are single-copy.

Homoplasy (recurrent mutation) issues: This exon is very conserved and does not exhibit repetitive sequence, compositional simplicity, or indels in any species in either paralog that could foster experimental error or alignment ambiguity. At position 15, the ancestral value is arginine in both paralogs. The G--> A transition to histidine in one individual is conservative under most circumstances (still basic) and arises from an arginine codon CpG hotspot conserved back to lamprey in 30 of 32 species with available data, yet histidine is not observed part of a reduced alphabet (ie R/H) at this position over many billions of years of branch length. Consequently R-->H is a significant change in this individual tasmanian devil.

Known variations: No human disease variants have been reported for either ERN2 or ERN1, probably attributable to essentiality. Site-specific mutation close to the exon here have been generated for K121P, D123P, W125A, and Q105E but only for ERN1. Naturally occuring coding SNPs in the human population relevent to the ERN2 exon are not known but low frequency alleles could emerge from the 1000 Genomes Project.

Side issues: a very ancient conserved leucine at position 21 appears to be transitioning to phenylalanine at marsupial node but has not been fixed, so settles out as L or F depending on lineage-sorting on each terminal marsupial leaf whereas placentals are all changed to phenylalanine (a phyloSNP caught in mid-air). While L and F might seem about the 'same' as amino acids, the branch length conservation totals say both are important but for different reasons: this is not a waffle codon nor reduced alphabet situation. This raises the question -- given the extreme conservation of this exon otherwise -- of whether the L-->F change at position 21 in both individuals has 'enabled' (made neutral or adaptive) an otherwise unfavorable R-->H change at position 15 in one individual.

Structural significance: By good fortune, the crystal structure of ERN1 (alternately called IRE1) has been published. The PDB 2HZ6 structure has good coverage of this particular exon. Consequently the marsupial ERN2 could be very accurately modelled and the structural effects of L-->F with or without R-->H computed by submission to online SwissProt modelling service.

Functional significance: A considerable amount is known about the paralog ERN1. Annotation transfer is likely applicable to ERN2. The two gene products differ primarily in expression -- ERN1 ubiquitious but ERN2 restricted to intestinal epithelial cells:

"The unfolded protein response (UPR) is an evolutionarily conserved mechanism by which all eukaryotic cells adapt to the accumulation of unfolded proteins in the endoplasmic reticulum (ER). Inositol-requiring kinase 1 (IRE1 or ERN1) and PKR-related ER kinase (PERK) are two type I transmembrane ER-localized protein kinase receptors that signal the UPR through a process that involves homodimerization and autophosphorylation... The monomer of the luminal domain comprises a unique fold of a triangular assembly of beta-sheet clusters. Structural analysis identified an extensive dimerization interface stabilized by hydrogen bonds and hydrophobic interactions... Mutations that disrupt the dimerization interface produced ERN1 protein that failed to either dimerize or activate the UPR upon ER stress."

"ERN1 is a type I transmembrane protein kinase receptor that also has a site-specific RNase activity that, upon activation, initiates a site-specific unconventional splicing reaction. The substrate for IRE1 RNase in metazoans is Xbp1 mRNA, which encodes a basic leucine zipper transcription factor of the ATF/CREB family. XBP1 controls expression of genes containing an X-box element or a UPR element in their promoter regions. The IRE1-mediated splicing reaction introduces into XBP1 an alternative C terminus, thereby generating an XBP1 molecule that is a more potent transcriptional activator. Therefore, activation of IRE1 and its RNase increases the transcription of genes encoding ER chaperones and folding catalysts... the ERN1 N-terminal luminal domain (NLD) functions as an ER stress sensor... under normal conditions IRE1 is maintained in a monomeric state through interaction of the NLD with the ER resident chaperone BiP. Upon ER stress, Grp78 binds to unfolded proteins as they accumulate, permitting the released NLD to form homodimers. Dimerization of the NLD in turn leads to the activation of the protein kinase and RNase activities in the cytosolic domain of ERN1."


ENR2 is readily distinguished from its ERN1 paralog at tBlastn by including the two following exons which bring percent identity to 62%:

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in two
tasmanian  devil (here one is identical and the other differs from Monodelphis by C->Y) and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. The sequences were assembled by Newbler (the official 454 assembler).

Pseudogene issues: No processed pseudogenes relevent to this exon are seen by Blat of human and opossum sequence. Some questionable sequence occurs in tarsier and sloth but may be due to low coverage read or assembly error. These fragmentary sequences also have cysteine at the position in question.

Paralog issues: This gene has a moderately similar paralog, MGAT5B, with a similar enzymatic role (beta1,6-N-acetylglucosaminyltransferase). The opossum MGAT5B protein differs at 12 positions out of 49 from opossum MGAT5, whereas human and marsupial MGAT5A differ at one residue. Consequently the two paralogs are readily distinguished within vertebrates. This is moot because 33 of 33 available MGAT5B also have cysteine at the position in question (data not shown).

Homoplasy (recurrent mutation) issues: The alignments below show tyrosine has never replaced cysteine in any other species. This cysteine is extremely invariant in both paralogs, tracing back to lophotrochozoa and cnidaria.

Known variations: No human disease alleles have been mapped to either paralog. None of 9 SNP tracks at the UCSC browser show human variation in this exon.

Side issues: The column marked with an asterisk in the difference alignment below indicates a non-conservative phyloSNP K-->I that occured in the theran mammal stem after platypus divergence. All three marsupial sequences including tasmanian devil have isoleucine in this position as do all 30 of the available placental mammal sequences, suggesting that both the lysine and the isoleucine continue to be under strong selection. No comparable shift occured in the theran stem for MGAT5B where the residue is arginine in all species, a basic residue similar to lysine.

Structural significance: The MGAT5 gene supposedly encodes a conventional enzyme, mannosyl (alpha-1,6-)-glycoprotein beta-1,6-N-acetyl-glucosaminyltransferase involved in the synthesis of protein-bound and lipid-bound oligosaccharides. Yet surprisingly, no determined 3D structure exists at PDB relevent to the configuration of this exon -- nor indeed the large 741 residue protein. This is very peculiar because glycosyl transerfases are a well-studied group of enzymes (nearly 100 loci in human) and might be expected to bind UDP-GlcNAc (like MGAT4A or MGAT3).

MGAT5.jpg

Only a small region of the protein have a prediction at ModBase using 2f9fA, a remote mannosyltransferasee from Archaeoglobus fulgidus. Luckily the model covers the cysteine at issue, showing two helices and a beta sheet.

SwissProt does not annotate the cysteine at position 532 as part of a disulfide or active site; the predicted location (Golgi) can have homodimer disulfides of similar enzymes, though this is a complex topic. Although all 20 cysteines in this protein are conserved human to opossum, this could be a consequence of the overall sequence identity of 90%. Twelve of the cysteines, not including the Sarcophilus variant, are found in the last 140 residues, perhaps forming a disulfide knot. All but 1 of these cysteines is conserved in the pre-Bilateran anemone Nematostella (which enriches relative to overall percent identity of 43%).

Highest MGAT5 expression occurs in brain, heart, kidney, and placenta. No domains other than a signal peptide and 6 of its own glycosylation target sites are found by online tools such as SMART.

Although the bulky tyrosine substitution is conservative in the sense of polar nature and perhaps hydrogen-bonding capacity, it cannot replace these specialized functions of cysteine. Considering the extreme conservation of this cysteine, this substitution must have a substantial-- perhaps even disabling -- impact on enzymatic function.

Functional significance: In view of the facial tumor situation in tasmanian devils, OMIM's account of prior research in mouse on this gene is quite interesting. Less is known about MGAT5B though it also functions in the synthesis of complex cell surface N-glycans.

" Malignant transformation is accompanied by increased beta-1,6-GlcNAc branching of N-glycans attached to Asn-X-Ser/Thr sequences in mature glycoproteins... The amount of MGAT5 products correlates with disease progression... Mgat5-deficient mice, which are born healthy but develop various abnormalities as adults...Mgat5-deficient mice showed kidney autoimmune disease, enhanced delayed-type hypersensitivity, and increased susceptibility to experimental autoimmune encephalomyelitis...The Golgi enzyme beta1,6 N-acetylglucosaminyltransferase V (Mgat5) is up-regulated in carcinomas and promotes the substitution of N-glycan with poly N-acetyllactosamine, the preferred ligand for galectin-3 (Gal-3)...inhibitors of MGAT5 might be useful in the treatment of malignancies by targeting their dependency on focal adhesion signaling for growth and metastasis."

MGAT5 has 16 exons. The key one here is 12. Alignment of MGAT5_sarHar to opossum shows only 5 differences in 589 residues available for comparison. 
Alignment of Monodelphis to human establishes that MGAT5 is better conserved than the average gene:

Full length genes appear available from GenBank and genome projects for mouse, rat (NM_001107068), dog (wgs exons), horse (XM_001489091), wallaby (wgs exons), and platypus (XM_001520380). Because this gene is 90% conserved at marsupial, placental mammals will not be informative -- indeed it is necessary to go to greater phylogenetic depth than lamprey to define the ultra-conserved residues in this protein:

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in
tasmanian  devil (in this case, one individual differs from Monodelphis by G->R), then differences between the two devils, and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. The sequences were assembled by Newbler.

The change from small non-polar glycine to bulky positively charged lysine is highly non-conservative, especially at a highly conserved residue such as this. Again the change in Sarcophilus is at a CpG hotspot, this time with a mildly unusual transversion of the C to the purine G.

The well-studied protein here is a member of a family of actin-related proteins (ARPs) which have significant homology to conventional actins, in particular sharing the actin fold (an ATP-binding cleft) as common feature. ACTL6B and its 83% identical paralog ACTL6A are involved in diverse cellular processes such as vesicular transport, spindle orientation, nuclear migration and chromatin remodeling. Both have 14 coding exons. The entire exon containing the G-->R is highly conserved including the glycine.

Pseudogene issues: Blat of full length sequence to human shows no recent processed or segmental pseudogenes. However more sensitive methods show a half dozen processed pseudogenes on different chromosomes plus one for ACTL6A. And opossum assembly, which has all 14 exons, also contains a fairly recent processed pseudogene with 91.5% identity. This locus has internal stop codons and ELSD in place of GLSG for the key glycine. This pseudogene arose from ACTL6A, not ACTL6B.

ACTL6B at chr17:77092347-77093972    ACTL6B at chr1:227633849-227635482

Sarcophilus also has one or more processed pseudogenes which considerably complicates the interpretation of tblastn output. However reads FP1I63R01ARR6N etc show two consecutive exons, the first of which is the G-->R version of the exon and the second identical to the following exon from opossum. The spacing between the two exons is 132 bp, more than adequate for a mammalian intron (whose lower limit is about 78 bp). Other reads span two exon for the normal version of the exon such as FKUJDAX01DZSZO etc again with same intron spacing. (Processed pseudogenes may later acquire pseudo-introns in the form of retroposons so RepeatMaskers needs to be run on the intervening sequence.)

Paralog issues: There is potential for confusion with the paralog ACTL6A. This wouldn't normally matter because all species in this gene too have glycine at the arginine-substituted site. However its pseudogene could present problems because its decay may have taken a different path in Sarcophilus than in Monodelphis giving the R (instead of D), assuming the pseudogene was formed prior to divergence of these species. Indeed, Macropus eugenii appears to have two processed pseudogenes; one of this has R in place of a glycine 4 residues earlier. It will prove necessary to consider adjacent regions in Sarcophilus reads to determine whether the feature is a pseudogene.

To summarize, this appears to be a valid coding SNP but the situation with paralogs, pseudogenes, and errors intrinsic to the 454 platform makes it unfavorable for rapid screening. It would be necessary to require matches of flanking intronic regions on both sides to be sure that the right locus is being investigated.

59 F=2(72) S=3(53)

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in
tasmanian  devil (in this case, both individuals differ from Monodelphis by  -> ), then differences between the two devils
(here one individual has S at position 59, the other has F), and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. 

Here the Ensembl-predicted sequence for opossum IPO7 is wrong. The exon begins with EELGSD... and the preceding residues are rubbish. The stop codon and N are thus extraneous.

Pseudogene issues: Human has 4 processed pseudogenes originating at various dates. However opossum lacks any detectable by Blat.

Homoplasy (recurrent mutation) issues: It can be seen from the 44-species alignment that the serine here is quite invariant, being conserved in all amniotes. In frog and all earlier diverging species, threonine is utilized. However serine is used in all vertebrates at the comparable position in the paralog IPO8 except for tetraodon which again uses threonine, as do weaker homologs in the protostomes Tribolium and Ixodes and cnidarians Nematostella and Acropora. This could be described as a reduced alphabet situation where the residue is strongly restricted to a small residue with hydroxyl side chain. Phenylalanine here, as in Sarcophilus, is thus an immensely non-conservative change as it is bulkly, unable to hydrogen bond, and unsuitable for the protein surface.

Known variations: No disease variants are known according to OMIM for either IPO7 or IPO8. No relevent structure at PDB has been determined for the central or distal region of the protein. The protein is quite large and thus it will be very difficult to predict the environment of the serine, much less the impact of phenylalanine substitution.

Side issues: Importin IPO7 has a broad and extremely important function in nuclear protein import, either autonomously as nuclear transport receptor or as an adapter in association with KPNB1. Havilng a receptor for nuclear localization signals, it can promote translocation of import substrates through the nuclear pore complex (NPC) by the energy requiring RAN-dependent mechanism. It mediates autonomously the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5, but in association with KPNB1 the import of five histones. The role of the paralog IPO8 is similar.

The question here is to what extent could IPO8 compensate for the S-->F change observed in Sarcophilus. It seems implausible given the divergence of the two proteins and the great conservation of IPO7 in the enveloping exon -- what selective force could maintain this if an auxillary gene is available to take on the nuclear import role?

Case of PPFIA3

 56 F=2(43) S=2(37)

Here both individuals differed from Monodelphis by S->F at position 56 of PPFIA3 with a confusing end to the exon.

Pseudogene issues: Not applicable.

Paralog issues: PPFIA3 (liprin) has 3 paralogs with considerable (but readily differentiable) sequence identity in this exon. These latter genes are more similar to each other than to PPFIA3, yet all 4 have S at the position occupied by F in tasmanian devil. The ancestral gene duplications must be quite old because lamprey has at least two copies and PPFIA3 itself is readily traced to shark.

PPFIA3 is missing in chicken and finch (proving it is not an essential gene in vertebrates) though present in lizard and frog. These latter species have a one residue mid-exon insert relative to mammals compensated for well past the key residue with a one residue deletion. All three species of marsupials with available data have an 8 residue insert three residues from the end of the exon (which still ends in phase 0 like all other orthologs). These indels have seriously affected the UCSC 44-species alignment quality. The batch of sequences immediately below are hand-curated directly from trace reads but otherwise are provided 'as is.'

The S-->F changed observed in tasmanian devil is likely very significant to protein function given the immense conservation of this residue and its flanking environment. However given the numerous independent indels still within this exon -- especially the 8 residue insert in the marsupial stem -- it would be difficult to argue that S-->F could not somehow be compensated with material impact on function. The complete loss of the gene in two birds (together these species have overwhelming trace coverage and many transcripts) establishes either that PPFIA3 lost its importance important or that one of its three paralogs can assume its function.

No structural data relevent to this exon exists at PDB. The entry at SwissProt shows two predicted phosphoserines within the exon but not at the serine here. Predicted domains and secondary structure coils are not applicable to this exon either. The function is somewhat understood: it may regulate the disassembly of focal adhesions, localize receptor-like tyrosine phosphatases type 2A at specific sites on the plasma membrane and forms homodimers and heterodimers with other liprins.

Tasmanian devil differs from Monodelphis by A->T at position 16. The variation observed later in the exon
is largely in opossum rather than other marsupials and occurs at positions with tight reduced alphabets.

Pseudogene issues: None.

Paralog issues: Some weak paralogs exist in human. These are poorly conserved in the region in question even about the key residue. While this weakens the overall invariance of the key residue, it also eliminates any possibility of cross-alignment to inappropriate homologs.

WDFY3	0	 WD repeat and FYVE domain containing 3 isoform
WDFY4	0	 WDFY family member 4
LYST	3e-114	 lysosomal trafficking regulator
NBEAL1	6e-109	 neurobeachin-like 1 isoform 1

LRBA	5e-100	 LPS-responsive vesicle trafficking, beach and
NBEA	3e-98	 eurobeachin
NSMAF	1e-78	 neutral sphingomyelinase (N-SMase) activation

Homoplasy (recurrent mutation) issues: None.

Known variations: Not a known disease gene; no relevent human variants known.

Side issues: None.

Structural significance: WDFY3 encodes a very large peripheral membrane protein of 3526 aa and 65 codinbg exons containing two leucine-rich repeats, a BEACH doman, five WD domains, a FYVE-domain,3 phosphotyrosines, 2 phosphoserine, and 1 phosphothreonine. However none of these are immediately relevent to the three exons centered on the SNP-containing exon. SuperFamily identifies the key exon significant matches (4e-09) as a concanavalin A-like lectin/glucanase domain. It co-localizes with autophagic structures in starved cells. The few transcripts that cover this region arise from testes (Xenopus), heart (chicken), early embryo (pig), and colon and hypothalamus (human), not informative as to function.

Functional significance: The substitution of threonine for alanine in proteins in general has quite mild effects. Alanine is the most generic amino acid and never catalytically active; threonine is polar but not charged and only somewhat bulkier. However the comparative genomics of this alanine in WDFY3 says this alanine is very different -- it is completely invariant over immense branch length back to chondrichthyes with the sole exception of Sarcophilus.

The embedding exon has more nearby variability than some of the other candidates. Its rather diverged paralog WDFY4 has leucine in place of alanine; this leucine is quite well conserved but has some exceptions. Note the alanine is not one of the better conserved residue patches in the overall region. Thus it appears that the substitution A-->T will have a significant effect on function but not a catastrophic one on core properties.

Discarded candidates

Below are three initial candidates that had to be discarded without detailed followup. One arose from repeated frameshifts in the critical region, another exhibited homoplasy with marsupials, and the third too extensive of an accepted reduced alphabet at the site. Thus while these three genes do not meeet the search criteria, they are nonetheless instructive in illustrating those criteria and making clear these are quite restrictive.

Here an I-->V change is seen in some tasmanian devils reads relative to opossum and wallaby. Here V is more typical of a theran mammal. Note I is also seen in armadillo, a placental, and A occurs in platypus and various other mammals. ACOT12, a acyl-CoA thioesterase, does not track back well in earlier diverging species. Because of the observed homoplasy, this locus is an unsuitable example of a significant amino acid change in Sarcophilus. However it illuminates the nature of suitable candidates and so is retained here.

Here the N-->K change is a non-conservative substitution in the sense asperagine is merely polar whereas lysine is bulkier and negatively charged. The N is highly invariant at this position back to teleost fish. FLI1 is a transcription factor associated with a leukemia virus integration site and Ewing sarcoma.

This would be a promising candidate except for the fact that the three reads establishing K clearly are plagued by frameshifts at the critical region. Possibly anomalous base composition is responsible here (ggatgagaagaacggcccccctcc) -- which is no doubt giving rising to transcriptional slippage generating homoplasic deletions of polyP -- or perhaps low coverage. This change is unlikely to be validated upon additional bulk or targeted sequencing because these lack motivating evidence.

Here two Sarcophilus reads show V-->I following residue 20 while three are V like opossum. It quickly emerges that wallaby also has I. Thus the change in tasmanian devil is within the normal reduced alphabet of this residue position. Various placentals show that T and M and even P are also accepted substituents here. Note too these are used clade-incoherently (eg primates alone are variable). Consequently this site is not under strong selection for V to begin with so SPON1 does not meet the selection criteria being used here.

Other marsupial genes of interest

The collections below contain well-understood genes with very extensive comparative genomics. They can serve as a test bed for Sarcophilus assembly quality, a place where genuine anomalies or distinct adaptive features might surface (perhaps as phyloSNPs) and where marsupial phylogeny might be refined using rare genomic events in nuclear genes. The gene sets contain all available marsupial orthologs plus for context one flanking gene each from placentals and monotremes. These genes are available in much broader hand-curated sets elsewhere on this site.

Scattered new data is available for other marsupials and monotremes from 454 reads, Sanger trace data and transcripts:

Didelphis virginiana       88,207 traces 248 nuc
Trichosurus vulpecula     169,115 traces 321 nuc  147,199 ests

IRBP (96 marsupials)

Interphotoreceptor retinol-binding protein, poorly named by IGNC as RBP3 despite its complete lack of paralogs, is a 4 exon 1247 residue glycoprotein that shuttles retinoids between the photoreceptor cells and the retinal pigment epithelium. The protein's size results from four ancient internal tandem duplictions that became established prior to the intronation era.

The first three homology domains and part of the fourth are all encoded by the first large exon of 1090 amino acids. This exon has been much used in marsupial phylogeny (along with the first intron of transthyretin). Indeed the 96 marsupial species in 51 genera having determined IRBP sequences at GenBank include a Dec 2008 partial sequence for Thylacinus cynocephalus, as well as for Sarcophilus harrisii.

The closest matches to the thylacine IRBP are shown in the difference alignment of the first 60 residues below. These species all lie with the Dasyuromorphia. The indicated E-->K may be one of several phyloSNPs breaking this group into blue and green subclades.

The numbat Myrmecobius fits implausibly (its amino terminal sequence EF028750 needs verification) -- its affinities seem to lie with the Didelphimorphia. Thylacinus is not basal within Dasyuromorphia relative to Myrmecobius using IRBP. However this may be a case of mis-comparison of genes.

Using Sarcophilus as probe in a different region, 721-900, we find this peculiar outcome: what appears to be a second very odd gene, XY difference, pseudogene, weird balanced polymorphism, nonhomologous recombination, sequence submission error, frameshifts, or systemic experimental error (eg Dasyurus maculatus AY532680 is identical to AY243439 outside the 15 amino acid block). However the genomic reads from individual Sarcophilus used in this project show no sign of this gene despite excellent coverage of the second type of gene.

Macropus and Monodelphis genomes only contain the second type of gene. All Didelphimorphia and Diprotodontia are of this type, as are platypus and all placentals. With the Sarcophilus genome, this can be resolved as it should have both and be the such first genome. Perhaps the alignment above is a mixture of type 1 and type 2 genes (resp. alleles). The Myrmecobius anomaly makes it more likely two distinct genes are present.

A definite pecularity seen in blast searches is the occurence earlier in the sequence of a very homologous segment for this very block, likely the homologous part of another of the internal tandem repeats. It is seen in both types of genes. Possibly internal non-homologus recombination or gene conversion has inserted first repeat sequence again in this distal block in place of what was relatively diverged sequence. Internal gene conversion would make IRBP extremely difficult to use in alignment-based phylogeny. As rare genomic event, it unites the species that have it but species that don't have it would have to be re-examined to exclude the possiblity that only the type 2 gene happened to be sequenced.

It emerges from direct tblastn that the Sacrophilus individual sequenced was female. That is, ATRX is well represented but not ATRY (though the situation is somewhat confused due to additional paralogs). Marsupial XY are quite different from placentals:

"Many or most genes on the mammal Y chromosome evolved a testis-specific function after diverging from an X-borne copy with a general function in both sexes. In marsupial but not eutherian mammals, a testis-specific orthologue (ATRY) of the widely expressed X-borne ATRX gene lies on the Y chromosome. Since mutations in human ATRX cause sex reversal, it is possible that one function of ATRY in marsupials is testicular differentiation. We report here the isolation and sequencing of the tammar wallaby (Macropus eugenii) ATRY cDNA, and comparison of its sequence with that of tammar ATRX. The evolution of a testis-specific function for the ATRY protein distinct from the general role of ATRX in both sexes has been accompanied by sequence changes in many protein domains that would alter protein binding partners. A large open reading frame encodes a 1771 amino acid ATRY protein that has diverged extensively from ATRX. The conservation and loss of particular motifs identify those required for testicular function (ATRY) and function in other tissues (ATRX)."

Rod rhodopsin RHO1 (4+ marsupials)

The optimal wavelength for scotopic (dim light) vision of Sarcophilus is easily predictable provided key tuning residues are covered by the assembly. The 97% match to Sminthopsis and agreement at tuning residues suggests this aspect of vision will be nearly identical between the two species.

Cone rhodopsin SWS2 (9+ marsupials)

Cone rhodopsin RHO2 has been lost in all mammals and no debris from this gene is expected in Sacrophilus). The short wavelength cone opsin SWS2, while still present in platypus, has also been lost in all theran opsin too long ago to leave detectable remnants in syntenic position. Cone opsin SWS1 has this turned around, being present in theran mammals but only as debris in platypus. A nearly full length gene, most simiilar to Sminthopsis, can be recovered from Sarcophilus read coverage.

Cone rhodopsin LWS (9+ marsupials)

This basal long wavelength imaging opsin is available from 97 vertebrates and has already been analyzed for phyloSNPs and rare genomic events. The Didelphimorphia experienced a 3-4 residue insert in exon 1 that separates them from all other marsupials. Note this region has quite a complicated indel history. The extra residues have repeat character DVNE DDND suggesting replication slippage. The gene is present and intact in Sarcophilus though two exons are not currently available. LWS in tasmanian devil is identical to the Sminthopsis ortholog.

Encephalopsin (2+ marsupials)

Pinopsin, parapinopsin, parietopsinand VA opsin all terminate in sauropods and are missing in all mammals. Encephalopsin has a very peculiar history of gene loss in tetrapods, requiring some seven independent and asynchronous events including platypus. While this limits the phylogenetic utility of any gene loss within marsupials, the status of the gene within Sarcophilus is still informative. A full length gene can be recovered with 94% identity to opossum, strongly indicating that encephalopsin is fully functional within Sarcophilus.

RGR opsin (0 marsupials)

This gene has apparently been lost specifically in the marsupial clade, though support for that is only provided by the Monodelphis and Macropus genome projects. It would be of considerable interest to find the gene or a fragment thereof in syntenic position in Sarcophilus. However nothing can be found with tblastn of current reads.

Peropsin (2+ marsupials)

Sarophillus can be expected to have this gene. Further, the protein sequence should substantiate the 4 previously defined phyloSNPs characteristic of the marsupial/placental transition.

Neuropsin (2+ marsupials)

Here Sarcophilus can be predicted to contain only NEUR1 because the ancient vertebrate genes NEUR2 and NEUR3 appear to terminate in sauropods and NEUR4 in platypus.

PRNP (3+ marsupials)

The Sarcophilus repeat region is of considerable interest -- the high GC content of this region makes it difficult to sequence and so provides a test of the 454 technology and Newbler assembler. This region consists in placentals a five octapeptide repeat, in marsupials and platypus a five nona- or decapeptide residue repeat that may resolve fine details of the marsupial phylogenetic tree, which in birds, lizards, turtles, frogs and fish is a hexapeptide repeat with trimeric internal substructure. Even though the single exon gene is clearly orthologous in all these species, the repeat regions within it are not directly comparable because they have expanded and contracted through replication slippage, plus experienced the odd repeat length change in marsupials and another in placentals.

The Sarcophilus prion gene has very high coverage that overcomes the occasional problem with frameshifts and allows the gene to be accurately tiled. However familiarity with the gene and reliable fiducial sequences are key to rapid assembly of the full length gene. No sequencing difficulties were observed in the high GC repeat region. The gene is very normal and has no indications whatsoever of abnormal numbers of repeats (4) or prion disease disposition.

The signal region of Sarcophilus PRNP is expected to show the same length as the other 3 known marsupial sequences, which is confirmed by the sequence. Placentals exhibit a one residue deletion relative to this ancestral length.

PRND (2+ marsupials)

Sarcophilus sequence for this intronless gene is a welcome addition to a limited existing set of early-diverging mammalian orthologs. With more data, the relative rates of divergence of PRND from its parental paralog PRNP could be compared in marsupial and placentals. It appears from the mere 75% identity between tasmanian devil and wallaby that doppels are diverging quite rapidly both from PRNP and from each other in the marsupial lineage, indicating some selectional pressure but not a hugely important function (that is, many residue positions have an increased reduced alphabet).
