OPN3, ili Opsin-3, je protein koji je kod čoveka kodiran OPN3 genom.^[1]^[2]^[3] Alternativno splajsovanje ovog gena proizvodi više transkriptnih varijanti, koje kodiraju različite proteinske izoforme.

Funkcija

Opsini su članovi familije G protein-spregnutih receptora. Osim vizuelnih opsina, sisari poseduje nekoliko fotoreceptivnih ne-vizuelnih opsina koji su izraženi u tkivima izvan oka. Gen opsina-3 je u znatnoj meri izražen u mozgu i testisima, a u maloj meri i u jetri, materici, srcu, plućima, skeletalnim mišima, bubrezima, i pankreasu. Ovaj gene isto tako može da bude izražen u mrežnjači. Ovaj protein poseduje kanoničke osobine fotoreceptivnih opsina.^[3]
