Sequence and evolution of the blue cone pigment gene in old and new world primates
- Univ. of London (United Kingdom); and others
The sequences of the blue cone photopigments in the talapoin monkey (Miopithecus talapoin), an Old World primate, and in the marmoset (Callithrix jacchus), a New World monkey, are presented. Both genes are composed of 5 exons separated by 4 introns. In this respect, they are identical to the human blue gene, and intron sizes are also similar. Based on the level of amino acid identity, both monkey pigments are members of the S branch of pigments. Alignment of these sequences with the human gene requires the insertion/deletion of two separate codons in exon 1. The silent site divergence between these primate blue genes indicates a separation of the Old and New World primate lineages around 43 million years ago. 41 refs., 1 fig., 3 tabs.
