T-plasminogen activator.
based on mapping to UniProt P00750
Specific cleavage of Arg-|-Val bond in plasminogen to form plasmin.
-!- 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. -!- Belongs to peptidase family S1. -!- Formerly EC 3.4.21.31 and EC 3.4.99.26.
