1 TABLE OF CONTENTS 1. Abstract
1. ABSTRACT Plasmin is a potent extracellular protease specialized in the degradation of fibrin (fibrinolysis). Active plasmin is generated by proteolytic activation of the zymogen plasminogen (Plg) by urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA). Alpha-enolase, although traditionally considered a glycolytic enzyme, constitutes a receptor for plasminogen on several cell types, serving to localize and promote plasminogen activation pericellularly. Localization of plasmin activity on the cell surface plays a critical role in fibrinolysis and in physiopathological processes involving extracellular matrix remodelling. |
