PAI-2 is an inhibitory serpin expressed mainly in keratinocytes, activated monocytes, and placental trophoblasts. It exists predominantly as a 47 kDa nonglycosylated intracellular protein which can be induced to be secreted as 60 kDa glycoprotein. The glycosylated and unglycosylated forms of PAI-2 are equally effective as inhibitors of urokinase-type plasminogen activator (uPA), the only established physiological target of this serpin. PAI-2 has a unique ability to form dormant polymers spontaneously and reversibly under physiological conditions. Alternative Names: Plasminogen Activator Inhibitor-2 protein, Urokinase Inhibitor protein, PAI 2, PAI-2 protein, PAI2, PAI-2 protein, PAI 2 protein, PAI-2
