  • FunctionThis inhibitor acts as 'bait' for tissue plasminogen activator, urokinase, and protein C. Its rapid interaction with TPA may function as a major control point in the regulation of fibrinolysis.
  • Tissue specificityFound in plasma and platelets and in endothelial, hepatoma and fibrosarcoma cells.
  • Involvement in diseaseDefects in SERPINE1 are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1D) [MIM:613329]. It is a hematologic disorder characterized by increased bleeding after trauma, injury, or surgery. Affected females have menorrhagia. The bleeding defect is due to increased fibrinolysis of fibrin blood clots due to deficiency of plasminogen activator inhibitor-1, which inhibits tissue and urinary activators of plasminogen.
    Note=High concentrations of SERPINE1 seem to contribute to the development of venous but not arterial occlusions.
  • Sequence similaritiesBelongs to the serpin family.
  • Post-translational
    Inactivated by proteolytic attack of the urokinase-type (u-PA) and the tissue-type (TPA), cleaving the 369-Arg-
    -Met-370 bond.
  • Cellular localizationSecreted.
