Proteinase-activated receptor 1 (PAR1) also known as the coagulation factor II (thrombin) receptor is a protein that in humans is encoded by the F2R gene. PAR1 is a G protein-coupled receptor involved in the regulation of thrombotic response. Proteolytic cleavage leads to the activation of the receptor.
Several selective antagonists for the PAR1 receptor have been developed, for use as anti-clotting agents for the treatment of heart disease.
