CC -!- FUNCTION: Photoreceptor required for image-forming vision at low light
CC intensity. Light-induced isomerization of 11-cis to all-trans retinal
CC triggers a conformational change that activates signaling via G-
CC proteins. Signaling mediates the activation of phospholipase C (By
CC similarity). Subsequent receptor phosphorylation mediates displacement
CC of the bound G-protein alpha subunit by arrestin and terminates
CC signaling (By similarity). {ECO:0000250|UniProtKB:P08100,
CC ECO:0000250|UniProtKB:P31356}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P31356}; Multi-
CC pass membrane protein {ECO:0000250|UniProtKB:P31356}. Note=Detected on
CC the rhabdomere membrane in the photoreceptor outer segment.
CC {ECO:0000250|UniProtKB:P31356}.
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 (By similarity). After hydrolysis of the Schiff base and
CC release of the covalently bound all-trans-retinal, active rhodopsin is
CC regenerated by binding of a fresh molecule of 11-cis-retinal (By
CC similarity). {ECO:0000250|UniProtKB:P02699,
CC ECO:0000250|UniProtKB:P31356}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. Opsin
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU00521}.
