Opn3 Gene Summary [Rat]
Predicted to enable 11-cis retinal binding activity; G protein-coupled photoreceptor activity; and all-trans retinal binding activity. Predicted to be involved in several processes, including cellular response to UV-A; positive regulation of D-glucose import; and regulation of melanin biosynthetic process. Predicted to be located in cytoplasm. Predicted to be active in photoreceptor outer segment and plasma membrane. Orthologous to human OPN3 (opsin 3).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Opn3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
