RGS16 (regulator of G protein signalling 16) negatively regulates G protein coupled receptor signalling. RGS16 inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP bound form. Binds to G(i) alpha and G(o) alpha, but not to G(s) alpha. May play a role in regulating the kinetics of signaling in the phototransduction cascade.
