==The multifunctional nature of Gbeta5/RGS9 revealed from its crystal structure==
-
Regulators of G-protein signaling (RGS) proteins enhance the intrinsic, GTPase activity of G protein alpha (Galpha) subunits and are vital for, proper signaling kinetics downstream of G protein-coupled receptors, (GPCRs). R7 subfamily RGS proteins specifically and obligately dimerize, with the atypical G protein beta5 (Gbeta5) subunit through an internal G, protein gamma (Ggamma)-subunit-like (GGL) domain. Here we present the, 1.95-A crystal structure of the Gbeta5-RGS9 complex, which is essential, for normal visual and neuronal signal transduction. This structure reveals, a canonical RGS domain that is functionally integrated within a molecular, complex that is poised for integration of multiple steps during G-protein, activation and deactivation.

== Function ==
 +
[https://www.uniprot.org/uniprot/RGS9_MOUSE RGS9_MOUSE] 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(t)-alpha. Involved in phototransduction; key element in the recovery phase of visual transduction.
