The Role of Heterotrimeric G Proteins in Platelet Activation
Citation Information: Biological Chemistry. Volume 381, Issue 5-6, Pages 389–396, ISSN (Print) 1431-6730, DOI: 10.1515/BC.2000.051, July 2005

Activation of platelets plays a central role in hemostasis as well as in various thromboembolic diseases like myocardial infarction or stroke. Most platelet activating stimuli function through receptors which couple to heterotrimeric G proteins of the Gi, Gq and G12 families. Recent studies have elucidated the roles of individual G proteins in the regulation of platelet functions like shape change, aggregation and granule secretion. The signaling pathways mediated by heterotrimeric G proteins operate synergistically to induce a full activation of platelets. This review summarizes recent progress in the understanding of upstream regulation of platelet activation through G protein-coupled receptors.
