A [auth R]PF000017 transmembrane receptor (rhodopsin family) (7tm_1)7 transmembrane receptor (rhodopsin family)This family contains, amongst other G-protein-coupled receptors (GCPRs), members of the opsin family, which have been considered to be typical members of the rhodopsin superfamily. They share several motifs, mainly the seven transmembrane helices, GC ...Domain
A [auth R]PF10413Amino terminal of the G-protein receptor rhodopsin (Rhodopsin_N)Amino terminal of the G-protein receptor rhodopsinRhodopsin is the archetypal G-protein-coupled receptor. Such receptors participate in virtually all physiological processes, as signalling molecules. They utilise heterotrimeric guanosine triphosphate (GTP)-binding proteins to transduce extracellular ...Domain
B [auth A]PF00503G-protein alpha subunit (G-alpha)G-protein alpha subunitG proteins couple receptors of extracellular signals to intracellular signaling pathways. The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like ...Domain
