Function

function

Enhances GTPase-activating protein (GAP) activity of regulator of G protein signaling (RGS) proteins, such as RGS7 and RGS9, hence involved in the termination of the signaling initiated by the G protein coupled receptors (GPCRs) by accelerating the GTP hydrolysis on the G-alpha subunits, thereby promoting their inactivation (By similarity).
Increases RGS7 GTPase-activating protein (GAP) activity, thereby regulating mood and cognition (By similarity).
Increases RGS9 GTPase-activating protein (GAP) activity, hence contributes to the deactivation of G protein signaling initiated by D2 dopamine receptors (By similarity).
May play an important role in neuronal signaling, including in the parasympathetic, but not sympathetic, control of heart rate (By similarity).

Interaction

Subunit

Component of a complex composed of RGS9 (isoform RGS9-1), GNB5 and RGS9BP; within this complex, the presence of GNB5 stabilizes both itself and RGS9 and increases RGS9 GTPase-activating protein (GAP) activity. Interacts with RGS7, forming the RGS7-GNB5 complex; within this complex, the presence of GNB5 increases RGS7 GTPase-activating protein (GAP) activity. Interacts with GPR158; promotes the GTPase activator activity of the RGS7-GNB5 complex in absence of glycine, in contrast GTPase activator activity of the RGS7-GNB5 complex is inhibited in presence of glycine. Interacts with RGS6.
