Predicted to enable G-protein beta-subunit binding activity and GTPase activity. Predicted to be involved in G protein-coupled receptor signaling pathway and positive regulation of cytosolic calcium ion concentration. Predicted to act upstream of or within signal transduction. Located in cell body; dendrite; and postsynaptic density. Is expressed in several structures, including gut; nervous system; oocyte; renal vasculature; and sensory organ. Orthologous to human GNG3 (G protein subunit gamma 3). [provided by Alliance of Genome Resources, Apr 2022]
