Description PAR-4 (1-6) (human) also called GYPGQV, Proteinase Activated Receptor 4 (1-6) (human), Thrombin Receptor-Like 3 (1-6) (human), Coagulation Factor II Receptor-Like 3 (1-6) (human), corresponds to the amino terminus of the fourth protease-activated receptor (PAR4) after the cleavage at Arg47/Gly48, it was tested for its ability to stimulate COS cells expressing PAR4. PAR-4 (1-6) (human) readily activated both wild-type and mutant PAR4 (R47A) at 500 µM, whereas thrombin and trypsin only activate the wild-type PAR4.
