tissue plasminogen activator meaning

Noun: tissue plasminogen activator

1. A thrombolytic agent (trade name Activase) that causes fibrinolysis at the site of a blood clot; used in treating acute myocardial infarction
   - Activase

Derived forms: tissue plasminogen activators

Type of: clot buster, thrombolytic, thrombolytic agent

Encyclopedia: Tissue plasminogen activator

[Medicine]
A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to PLASMIN. It has fibrin-binding activity and is immunologically different from URINARY PLASMINOGEN ACTIVATOR. The primary sequence,composed of 527 amino acids,is identical in both the naturally occurring and synthetic proteases. EC 3.4.21.68.n : a clot-dissolving enzyme with an affinity for fibrin that is produced naturally in blood vessel linings and is used in a genetically engineered form to prevent damage to heart muscle following a heart attack —abbr.
