Key result
A G184S substitution in Gi2α enhanced platelet aggregation in vitro and increased platelet accumulation after vascular injury, demonstrating an active role for RGS proteins in regulating platelets.

Should not yet inform clinical platelet management; extends preclinical evidence for RGS proteins in hemostasis.
RGS proteins actively regulate platelet responsiveness and limit the magnitude of the normal hemostatic response by modulating Gi2-dependent signaling.
Signarvic et al. (2010) studied Platelet activation and thrombus formation. G184S substitution in Gi2α (blocking RGS/Gi2 interactions) vs. Wild-type (implied) was evaluated on Platelet aggregation in vitro and platelet accumulation after vascular injury. A G184S substitution in Gi2α enhanced platelet aggregation in vitro and increased platelet accumulation after vascular injury, demonstrating an active role for RGS proteins in regulating platelets.
