| D [auth R] | PF00001 | 7 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 |
| PF00503 | G-protein alpha subunit (G-alpha) | G-protein alpha subunit | G 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 |
