Predicted to enable G-protein alpha-subunit binding activity and GTPase activator activity. Predicted to be involved in termination of G protein-coupled receptor signaling pathway. Predicted to be located in several cellular components, including apical dendrite; neuronal cell body; and nuclear lumen. Predicted to be part of protein-containing complex. Predicted to colocalize with synapse. Is expressed in several structures, including female reproductive system; heart; lung; nervous system; and trunk. Orthologous to human RGS12 (regulator of G protein signaling 12). [provided by Alliance of Genome Resources, Apr 2022]
