ab94070 is a 293T cell transfected lysate in which Human PAI1 has been transiently over-expressed using a pCMV-PAI1 plasmid. The lysate is provided in 1X Sample Buffer.
Note: For more detailed how the transfected lysate was prepared view preparation notes
Disease: Defects 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.
Function: This 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.
PTM: Inactivated by proteolytic attack of the urokinase-type (u-PA) and the tissue-type (TPA), cleaving the 369-Arg-
Similarity: Belongs to the serpin family.
Tissue specificity: Found in plasma and platelets and in endothelial, hepatoma and fibrosarcoma cells.
