Protein

Rhodopsin

Gene

RHO

Organism
Alloteuthis subulata (Squid) (Loligo subulata)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Visual pigments such as rhodopsin and porphyropsin are light-absorbing molecules that mediate vision. Rhodopsin consists of an apoprotein, opsin, covalently linked to 11-cis-retinal. This receptor is coupled to the activation of phospholipase C. Porphyropsin consists of opsin covalently linked to 11-cis 3,4-didehydroretinal.
