NCIt definition : Tissue-type plasminogen activator (562 aa, 63 kDa) is encoded by the human PLAT gene.
This protein plays a role in the cleavage of plasminogen between Arg-580 and Val-581
to form the fibrinolytic enzyme plasmin.;
Alternative definition : NCI-GLOSS: An enzyme made in the body that helps dissolve blood clots. A form of this
enzyme is made in the laboratory to treat heart attacks, strokes, and clots in the
lungs. It is also being studied in the treatment of cancer. Tissue plasminogen activator
is a type of systemic thrombolytic agent.;
NCIt note : Tissue-type plasminogen activator is synthesized as a single chain which is cleaved
by plasmin, tissue kallikrein or factor Xa to a two chain disulfide linked protein.
The two chain form demonstrates increased levels of plasminogen-plasmin converting
activity when compared to the single chain form.;
