| Description | PAR1 (1-6) is a hexapeptide that corresponds to amino acid residues 1-6 of the amino terminal tethered ligand sequence of mouse and rat proteinase-activated receptor 1 (PAR1), residues 42-47 of the full-length mouse sequence, and residues 46-51 of the full-length rat sequence.1,2 PAR1 is a high-affinity thrombin receptor that induces platelet activation and deposition into thrombi as well as smooth muscle mitogenesis.3 Unlike thrombin, PAR1 (1-6) acts as an agonist of PAR1 in smooth muscle cells but is inactive in rodent platelets.4 It increases mitogenesis and the expression of the IGF-1 receptor (IGF-1R) by 47% in vascular smooth muscle cells (VSMCs), an effect that is inhibited by the thrombin inhibitor hirudin and by the protein tyrosine kinase inhibitor genistein (Item No. 10005167).2 PAR1 (1-6) increases histamine and β-hexosaminidase release from rat peritoneal mast cells in a concentration-dependent manner, with the maximum release at a concentration of 50 µM.1 It also mimics the effect of thrombin, increasing swelling-activated efflux of [3H]glutamate induced by hypoosmotic medium in astrocytes in vitro when used at concentrations ranging from 5 to 10 µM.5WARNING This product is not for human or veterinary use. | | References | [1] TAMARA N.
