Abstract
Regulation of plasminogen activation is a key process in controlling proteolytic events in the extracellular matrix (ECM) and this regulation is achieved through the action of specific plasminogen activator (PA) inhibitors (PAIs). Type I PAI (PAI-1) is the physiological inhibitor both of urinary-type PA (u-PA) and tissue-type PA (t-PA) (Loskutoff et al., 1989) and is a major component of the ECM of cultured cells. This inhibitor may protect ECM constituents against cellular proteases and thus influence the cell migration and tissue destruction that occurs during development, inflammation and tumor metastasis. In this review, we discuss the properties of PAI-1 and the evidence that the binding of PAI-1 to ECM is mediated by serum-derived vitronectin (Vn).
