FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the regulator of G-protein signaling family. This protein is contains a conserved, 120 amino acid motif called the RGS domain. The protein attenuates the signaling activity of G-proteins by binding to activated, GTP-bound G alpha subunits and acting as a GTPase activating protein (GAP), increasing the rate of conversion of the GTP to GDP. This hydrolysis allows the G alpha subunits to bind G beta/gamma subunit heterodimers, forming inactive G-protein heterotrimers, thereby terminating the signal. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a null allele show reduced thermal nociception threshold, increased startle reflex, thrombocytopenia, defective megakaryopoiesis, and increased platelet aggregation. Homozygotes for a different null allele show decreased bleeding time, increased platelet aggregation, and thrombosis. [provided by MGI curators]
