Webby thrombin, and sensing thrombin is likely, at least in part, their role in vivo (see text). One receptor, PAR2, is activated by trypsin and tryptase but not by thrombin. Its roles in vivo remain to be explored. The four PAR genes share a common two-exon structure. In essence, the first exon encodes a signal peptide and the second the mature WebNational Center for Biotechnology Information

However, peptides corresponding to the tethered ligand … WebMoreover, the thrombin-activated PAR1-PAR2 dimer signals via β-arrestins and Rac1, rather than G proteins and RhoA signaling mediated by the receptor protomer. These studies suggest that in addition to different proteases that cleave at distinct sites in the PAR1 N terminus, other receptor properties can influence signaling, including ...

WebPAR-4 is activated by thrombin or a synthetic peptide that mimics its tethered ligand (GYPGKF). In human platelets, PAR-1 and PAR-4 account for most (if not all) of thrombin's actions. PAR-1 induces rapid and robust platelet responses; PAR-1 contains a hirudin-like domain adjacent to the thrombin cleavage site, binds thrombin with high affinity ... gloss wyconWebcoagulation factor II (thrombin) receptor-like 1 Receptor for trypsin and trypsin-like enzymes coupled to G proteins.
