CC -!- FUNCTION: Photoreceptor required for image-forming vision at low light
CC intensity. Can use both retinal and 3-dehydroretinal as visual pigment.
CC Light-induced isomerization of 11-cis to all-trans retinal triggers a
CC conformational change that activates signaling via G-proteins.
CC Signaling via GNAQ probably mediates the activation of phospholipase C.
CC {ECO:0000250|UniProtKB:P35356}.
CC -!- SUBUNIT: Homodimer. Interacts with GNAQ.
CC {ECO:0000250|UniProtKB:P35356}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P35356}; 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:P35356}.
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}.
