Regulator of G-protein signaling 6 (RGS6)

Regulates G protein-coupled receptor signaling cascades. Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form.

The RGS6/GNB5 dimer enriches GNAO1 GTPase activity (PubMed:10521509). .
