Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal (By similarity). Required for the maintenance of cone outer segment organization in the ventral retina, but not essential for the maintenance of functioning cone photoreceptors (PubMed:21219924, PubMed:25416279). Involved in ensuring correct abundance and localization of retinal membrane proteins (PubMed:25416279). May increase spectral sensitivity in dim light (PubMed:11055434).

Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.
