CC -!- FUNCTION: Photoreceptor required for image-forming vision at low light
CC intensity. While most salt water fish species use retinal as
CC chromophore, most freshwater fish use 3-dehydroretinal, or a mixture of
CC retinal and 3-dehydroretinal (By similarity). Light-induced
CC isomerization of 11-cis to all-trans retinal triggers a conformational
CC change that activates signaling via G-proteins. Subsequent receptor
CC phosphorylation mediates displacement of the bound G-protein alpha
CC subunit by arrestin and terminates signaling (By similarity).
CC {ECO:0000250|UniProtKB:P02699, ECO:0000250|UniProtKB:P08100,
CC ECO:0000250|UniProtKB:P32309}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P08100}; Multi-
CC pass membrane protein {ECO:0000250|UniProtKB:P08100}. Cell projection,
CC cilium, photoreceptor outer segment {ECO:0000250|UniProtKB:P35359}.
CC Note=Synthesized in the inner segment (IS) of rod photoreceptor cells
CC before vectorial transport to disk membranes in the rod outer segment
CC (OS) photosensory cilia. {ECO:0000250|UniProtKB:P08100}.
CC -!- PTM: Phosphorylated on some or all of the serine and threonine residues
CC present in the C-terminal region. {ECO:0000250|UniProtKB:P02699}.
CC -!- PTM: Contains one covalently linked retinal chromophore.
CC {ECO:0000250|UniProtKB:P02699}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. Opsin
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU00521}.
