UniprotKB/SwissProt ID: O42604 (O42604)
Gene Name:
rho
Organism: Zeus faber (John Dory)
Function: Photoreceptor required for image-forming vision at low light intensity. While most salt water fish species use retinal as chromophore, most freshwater fish use 3-dehydroretinal, or a mixture of retinal and 3-dehydroretinal (PubMed:18422881). Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change that activates signaling via G-proteins. Subsequent receptor phosphorylation mediates displacement of the bound G-protein alpha subunit by arrestin and terminates signaling (By similarity)

Protein Subcellular Localization: Membrane. Cell projection, cilium, photoreceptor outer segment
