The Molecular Basis for Anti-Proteolytic and Non-Proteolytic Functions of Plasminogen Activator Inhibitor Type-1: Roles of the Reactive Centre Loop, the Shutter Region, the Flexible Joint Region and the Small Serpin Fragment

Abstract excerpt

The serine proteinase inhibitor plasminogen activator inhibitor type-1 (PAI-1) is the primary physiological inhibitor of the tissue-type and the urokinase-type plasminogen activator (tPA and uPA, respectively) and as such an important regulator of proteolytic events taking place in the circulation and in the extracellular matrix. Moreover, a few non-proteolytic functions have been ascribed to PAI-1, mediated by...
