- Description
- Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Predicted to be involved in G protein-coupled adenosine receptor signaling pathway; adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway; and gamma-aminobutyric acid signaling pathway. Predicted to act upstream of or within adenylate cyclase-modulating G protein-coupled receptor signaling pathway and cell division. Predicted to be located in centrosome and plasma membrane. Predicted to be part of heterotrimeric G-protein complex. Predicted to be active in cytoplasm. Is expressed in several structures, including barbel; lip; nervous system; neural tube; and tail bud. Orthologous to human GNAI2 (G protein subunit alpha i2).
