Reconstitution of ancestral green visual pigments of zebrafish and molecular mechanism of their spectral differentiation.

Molecular biology and evolution - 1 Apr 2005

Chinen Akito, Matsumoto Yoshifumi, Kawamura Shoji

Abstract excerpt

We previously reported that zebrafish have four tandemly duplicated green (RH2) opsin genes (RH2-1, RH2-2, RH2-3, and RH2-4). Absorption spectra vary widely among the four photopigments reconstituted with 11-cis retinal, with their peak absorption spectra (lambda(max)) being 467, 476, 488, and 505 nm, respectively. In this study, we inferred the ancestral amino acid (aa) sequences of the zebrafish RH2 opsins by...
