STRUCTURE OF THE REGULATOR OF G-PROTEIN SIGNALING 16

Template:ABSTRACT PUBMED 18434541

Function

[RGS16_HUMAN] 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.

About this Structure
