Function[OPSD_BOVIN] Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal (By similarity).[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedActivation of G-protein coupled receptors (GPCR) is not yet understood. A recent structure showed most of rhodopsin in the ground (not activated) state of the GPCR, but the cytoplasmic face, which couples to the G protein in signal transduction, was not well-defined. We have determined an experimental three-dimensional structure for rhodopsin in the unactivated state, which shows good agreement with the crystal structure in the transmembrane domain. This new structure defines the cytoplasmic face of rhodopsin. The G-protein binding site can be mapped. The same experimental approach yields a preliminary structure of the cytoplasmic face in the activated (metarhodopsin II) receptor. Differences between the two structures suggest how the receptor is activated to couple with transducin. Studies on the structure of the G-protein-coupled receptor rhodopsin including the putative G-protein binding site in unactivated and activated forms.,Yeagle PL, Choi G, Albert AD Biochemistry. 2001 Oct 2;40(39):11932-7.
