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 cellular response to dopamine; regulation of localization; and regulation of locomotion. Located in axon; cell cortex; and neuronal cell body. Expressed in several structures, including vulval cell. Human ortholog(s) of this gene implicated in several diseases, including Sturge-Weber syndrome; autosomal dominant hypocalcemia 2; and familial hypocalciuric hypercalcemia 2. Is an ortholog of human GNA11 (G protein subunit alpha 11).
