The Rgs9 complex acts as a GTPase activator protein (GAP) to further promote the alpha transducin GTPase activity and the hydrolysis of GTP leading to deactivation of the Galpha subunit, dissociation from the inihibitory PDE gamma subunit and re-association with the beta/gamma transducin subunits. The members of the Rgs9 complex are listed with aliases in parentheses, full names and links to gene report pages:

Rgs9 (PERRS) – regulator of G-protein signaling 9
Rgs9bp (R9AP) – regulator of G protein signaling 8 binding protein
Gnb5 (GB5) – G protein subunit beta 5
