Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in several processes, including G protein-coupled receptor signaling pathway; positive regulation of cell population proliferation; and regulation of signal transduction. Located in several cellular components, including cytosol; membrane raft; and nucleus. Used to study hypertension. Biomarker of hypertension. Orthologous to human GNAI2 (G protein subunit alpha i2).
