Introduction to Melanopsin Evolution

(more shortly)

Melanopsin MEL1 retention with exon loss in mammals

Melanopsin is an ancient rhabodomeric Gq opsin that persists all examined extant deuterostomes (which otherwise use ciliary opsins and the peropsin-group opsins). The melanopsins in earlier diverging clades are remarkable for their greatly extended C-terminal extension whose location is presumably cytoplasmic and whose function is quite unknown. This extenstion has undergone rapid change in post-frog species such as birds and lizards resulting in novel exons, diminished distal homology -- and in mammals, complete loss of terminal exons and any functionality that they provided. Less drastic length alterations occur at the amino terminus as well and indels are far more common than in other opsin families. This raises questions about what lies behind these dramatic shifts.


Melanopsin MEL2 gene loss in mammals

A paralogous second melanopsin in nonmammalian vertebrates was found quite recently by Bellingham et al. This evidently arose prior to divergence of telost fish by a segmental duplication because some evidence of flanking synteny survives. It cannot have arisen by the whole genome duplication in fish because that would not have descended to frog, lizards, and birds. No sign of this second gene can be found in platypus, marsupials, or placental mammals -- yet another longstanding functional opsin gene lost in this clade.
