Predicted to enable G-protein alpha-subunit binding activity and GTPase activator activity. Predicted to be involved in G protein-coupled acetylcholine receptor signaling pathway and positive regulation of GTPase activity. Predicted to act upstream of or within negative regulation of signal transduction. Predicted to be located in several cellular components, including axon terminus; dendritic spine; and neuronal cell body. Is expressed in brain; early conceptus; and secondary oocyte. Orthologous to human RGS10 (regulator of G protein signaling 10). [provided by Alliance of Genome Resources, Apr 2022]
