Summary

Description
Serine protease. Activates thrombin by cleavage of prothrombin. Does not activate factor X. When injected into rats, causes thrombus formation, fibrinogen depletion, uncoagulable blood, decreased platelet count, inhibition of collagen-induced platelet aggregation, leukocyte infiltration in lungs, congestion and hemorrhage in renal glomeruli and necrosis in renal distal tubules. Causes increase in surface expression of ICAM-1 and E-selectin on human umbilical vein endothelial cells, but does not affect expression of VCAM-1, or the expression of mediators involved in coagulation and fibrinolysis systems (TF, vWF and t-PA). Increases expression of the platelet activation inhibitors NO and PGI2. Increases viability of human umbilical vein endothelial cells, and inhibits apoptosis.
Biophysicochemical Properties
