| B [auth A] | 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 |
