CC -!- FUNCTION: Photoreceptor required for image-forming vision at low light
CC intensity. Required for photoreceptor cell viability after birth (By
CC similarity). Light-induced isomerization of 11-cis to all-trans retinal
CC triggers a conformational change that activates signaling via G-
CC proteins. Subsequent receptor phosphorylation mediates displacement of
CC the bound G-protein alpha subunit by arrestin and terminates signaling
CC (By similarity). {ECO:0000250|UniProtKB:P02699,
CC ECO:0000250|UniProtKB:P08100}.
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:P08100}.
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: Contains one covalently linked retinal chromophore. Upon light
CC absorption, the covalently bound 11-cis-retinal is converted to all-
CC trans-retinal. After hydrolysis of the Schiff base and release of the
CC covalently bound all-trans-retinal, active rhodopsin is regenerated by
CC binding of a fresh molecule of 11-cis-retinal.
CC {ECO:0000250|UniProtKB:P02699}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. Opsin
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU00521}.
