Functioni

Plasmin dissolves the fibrin of blood clots and acts as a proteolytic factor in a variety of other processes including embryonic development, tissue remodeling, tumor invasion, and inflammation. In ovulation, weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1 and C5. Cleavage of fibronectin and laminin leads to cell detachment and apoptosis. Also cleaves fibrin, thrombospondin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4. Binds to cells (By similarity).By similarity
Angiostatin is an angiogenesis inhibitor that blocks neovascularization and growth of experimental primary and metastatic tumors in vivo.By similarity

Catalytic activityi

Preferential cleavage: Lys-|-Xaa > Arg-|-Xaa; higher selectivity than trypsin. Converts fibrin into soluble products.

Enzyme regulationi

Converted into plasmin by plasminogen activators, both plasminogen and its activator being bound to fibrin. Cannot be activated with streptokinase.

Interactioni

Subunit structurei

Interacts (both mature PLG and the angiostatin peptide) with AMOT and CSPG4. Interacts (via the Kringle domains) with HRG; the interaction tethers PLG to the cell surface and enhances its activation. Interacts (via Kringle 4 domain) with ADA; the interaction stimulates PLG activation when in complex with DPP4. Angiostatin: Interacts with ATP5A1; the interaction inhibits most of the angiogenic effects of angiostatin.By similarity

Plasmin is inactivated by alpha-2-antiplasmin immediately after dissociation from the clot.
In the presence of the inhibitor, the activation involves only cleavage after Arg-581, resulting in 2 chains held together by 2 disulfide bonds. Without the inhibitor, the activation involves also removal of the activation peptide (By similarity).By similarity
