Accepted name: t-plasminogen activator
Reaction: Specific cleavage of Arg┼Val bond in plasminogen to form plasmin
Other name(s): tissue plasminogen activator; plasminogen activator, tissue-type; tissue-type plasminogen activator; tPA; t-PA
Comments: A peptidase of family S1 (trypsin family) from a wide variety of mammalian tissues, especially endothelial cells. Secreted as a single chain precursor which is cleaved to a two-chain form by plasmin. Activity is considerably enhanced by fibrin. Formerly included in EC and EC
