Enables G-protein alpha-subunit binding activity and G-protein beta-subunit binding activity. Involved in several processes, including positive regulation of potassium ion transmembrane transport; response to amphetamine; and response to ethanol. Located in several cellular components, including cytosol; membrane raft; and nuclear envelope. Part of protein-containing complex. Orthologous to human RGS7 (regulator of G protein signaling 7).
