Vertebrate (CRALBP) and Drosophila (PINTA) proteins with a CRAL-TRIO domain transport retinal-based chromophores that bind to opsin proteins and are necessary for phototransduction. The CRAL-TRIO domain gene family is composed of genes that encode proteins with a common N-terminal structural domain. While there is an expansion of this gene family in Lepidoptera, there is no lepidopteran ortholog of pinta. Read More
