Positive selection and functional divergence after melanopsin gene duplication.

Biochemical genetics - 1 Apr 2012

Dong Changgui, Zhang Junpeng, Qiao Jian, He Guimei

Abstract excerpt

A newly discovered melanopsin gene (Opn4) encodes a member of the opsins, melanopsin. Two melanopsin genes, mammalian-like Opn4m and Xenopus-like Opn4x, have been described in nonmammalian vertebrates, but the underlying evolutionary mechanisms behind the duplication of melanopsin genes remain unclear. We conducted a comprehensive evolutionary analysis within a phylogenetic framework. In our phylogenetic tree,...
