Gene: GNAO1 (G protein subunit alpha o1) Homo sapiens
Symbol: GNAO1
Name: G protein subunit alpha o1
Description: Predicted to have G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Predicted to be involved in adenylate cyclase-modulating G protein-coupled receptor signaling pathway and dopamine receptor signaling pathway. Predicted to localize to the heterotrimeric G-protein complex. Implicated in early infantile epileptic encephalopathy 17.
Type: protein-coding
RefSeq Status: REVIEWED
