Many Regulators of G protein Signaling (RGS) proteins accelerate the intrinsic GTPase activity of G(ialpha) and G(qalpha)-subunits [i.e., behave as GTPase-activating proteins (GAPs)] and several act(More)
Regulator of G-protein signaling 3 (RGS3) enhances the intrinsic rate at which Galpha(i) and Galpha(q) hydrolyze GTP to GDP, thereby limiting the duration in which GTP-Galpha(i) and GTP-Galpha(q) can(More)
The odorant-induced accumulation of cAMP can be inhibited by antibodies directed against G alpha s/olf. In contrast, antibodies raised against G alpha i-subunits caused a strong enhancement of the(More)
