OPN3 Gene
RNA expression pattern

Opsin-3 is a protein that, in humans, is encoded by the OPN3 gene.[1][2][3] Alternative splicing of this gene results in multiple transcript variants encoding different protein isoforms.

Function

Opsins are members of the G protein-coupled receptor superfamily. In addition to the visual opsins, mammals possess several photoreceptive non-visual opsins that are expressed in tissues outside the eye. The opsin-3 gene is strongly expressed in brain and testis and weakly expressed in liver, placenta, heart, lung, skeletal muscle, kidney, and pancreas. The gene may also be expressed in the retina. The protein has the canonical features of a photoreceptive opsin protein.[3]
