Within the vertebrate eye, betagamma crystallins are extremely stable lens proteins that are uniquely adapted to increase refractory power while maintaining transparency. Unlike alpha crystallins, which are well-characterized, multifunctional proteins that have important functions both in and out of the lens, betagamma lens crystallins are a diverse group of proteins with no clear ancestral or contemporary nonlens role. We carried out phylogenetic and molecular evolutionary analyses of the… Expand
