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. Predicted to localize to heterotrimeric G-protein complex. Is expressed in several structures, including barbel; lip; nervous system; neural tube; and tail bud. Orthologous to human GNAI2 (G protein subunit alpha i2).
