Type 1 plasminogen activator inhibitor binds to fibrin via vitronectin.
Type 1 plasminogen activator inhibitor (PAI-1), the primary inhibitor of tissue-type plasminogen activator (t-PA), circulates as a complex with the abundant plasma glycoprotein, vitronectin. This interaction stabilizes the inhibitor in its active conformation In this report, the effects of vitronectin on the interactions of PAI-1 with fibrin clots were studied. Confocal microscopic imaging of p...
متن کاملSerum Level of Plasminogen Activator Inhibitor Type-1 in Addicted Patients with Coronary Artery Disease
Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...

متن کاملInteraction of plasminogen activator inhibitor type-1 (PAI-1) with vitronectin.
The serpin plasminogen activator inhibitor type 1 (PAI-1) plays an important role in physiological processes such as thrombolysis and fibrinolysis, as well as pathophysiological processes such as thrombosis, tumor invasion and metastasis. In addition to inhibiting serine proteases, mainly tissue-type (tPA) and urokinase-type (uPA) plasminogen activators, PAI-1 interacts with different component...
متن کاملSerum-derived vitronectin influences the pericellular distribution of type 1 plasminogen activator inhibitor
Bovine aortic endothelial cells (BAEs) were used as a model system to study the nature and origin of protein(s) in the extracellular matrix that bind to type 1 plasminogen activator inhibitor (PAI-1). Matrix samples were fractionated by SDS-PAGE and analyzed by PAI-1 ligand binding and by immunoblotting using antibodies to vitronectin (Vn). PAI-1 bound primarily to two Vn-related polypeptides o...
