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 the arrestin SAG and terminates
CC       signaling (By similarity). {ECO:0000250|UniProtKB:P02699,
CC       ECO:0000250|UniProtKB:P08100}.
CC   -!- SUBUNIT: Homodimer (By similarity). May form a complex composed of RHO,
CC       GRK1 and RCVRN in a Ca(2+)-dependent manner; RCVRN prevents the
CC       interaction between GRK1 and RHO (By similarity). Interacts with GRK1
CC       (By similarity). Interacts (phosphorylated form) with SAG. Interacts
CC       with GNAT1. Interacts with GNAT3. SAG and G-proteins compete for a
CC       common binding site (By similarity). Interacts with PRCD; the
CC       interaction promotes PRCD stability. {ECO:0000250|UniProtKB:P02699,
CC       ECO:0000250|UniProtKB:P08100}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P02699}; Multi-
CC       pass membrane protein {ECO:0000250|UniProtKB:P02699}. Cell projection,
CC       cilium, photoreceptor outer segment {ECO:0000250|UniProtKB:P02699}.
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. 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}.
