a secreted protein that 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. Belongs to the serpin family. Interacts with VTN. Binds LRP1B; binding is followed by internalization and degradation. Plasma levels of PAI-1 and VCAM-1 together may be useful in predicting post-operative recurrence in patients with colorectal cancer. Note: This description may include information from UniProtKB.
