Tissue plasminogen activator - Wiki

Mar 04, 2021·Tissue plasminogen activator (abbreviated tPA or PLAT) is a protein involved in the breakdown of blood clots. It is a serine protease ( EC 3.4.21.68) found on endothelial cells, the cells that line the blood vessels. As an enzyme, it catalyzes the conversion of plasminogen to plasmin, the major enzyme responsible for clot breakdown.

tissue plasminogen activator (TPA, t-PA) (t-plasminogen activator) a serine endopeptidase synthesized by endothelial cells, the major physiologic activator of plasminogen; when bound to fibrin clots it catalyzes the conversion of plasminogen to plasmin by hydrolysis of a specific arginine-valine bond. It can be produced by recombinant technology for use in thrombolytic therapy.
