Predicted to enable D5 dopamine receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in adenylate cyclase-modulating G protein-coupled receptor signaling pathway; multicellular organism aging; and regulation of blood pressure. Acts upstream of or within several processes, including Rho protein signal transduction; branching involved in blood vessel morphogenesis; and platelet activation. Located in cytoplasm and nucleus. Is expressed in several structures, including branchial arch; genitourinary system; gut gland; nervous system; and sensory organ. Orthologous to human GNA13 (G protein subunit alpha 13).
