CC   -!- FUNCTION: Enhances GTPase-activating protein (GAP) activity of
CC       regulator of G protein signaling (RGS) proteins, hence involved in the
CC       termination of the signaling initiated by the G protein coupled
CC       receptors (GPCRs) by accelerating the GTP hydrolysis on the G-alpha
CC       subunits, thereby promoting their inactivation (Probable). Increases
CC       RGS9 GTPase-activating protein (GAP) activity, hence contributes to the
CC       deactivation of G protein signaling initiated by D(2) dopamine
CC       receptors (By similarity). May play an important role in neuronal
CC       signaling, including in the parasympathetic, but not sympathetic,
CC       control of heart rate (By similarity). {ECO:0000250|UniProtKB:A1L271,
CC       ECO:0000250|UniProtKB:O14775, ECO:0000305}.
CC   -!- SUBUNIT: Component of a complex composed of RGS9, GNB5 and RGS9BP;
CC       within this complex, the presence of GNB5 stabilizes both itself and
CC       RGS9 and increases RGS9 GTPase-activating protein (GAP) activity (By
CC       similarity). Interacts with RGS6 and RGS7 (By similarity).
CC       {ECO:0000250|UniProtKB:O14775, ECO:0000250|UniProtKB:P62881}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:P62881}.
CC   -!- SIMILARITY: Belongs to the WD repeat G protein beta family.
CC       {ECO:0000305}.
