Function
function
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.
Catalytic activity
Activity regulation
Converted into plasmin by plasminogen activators, both plasminogen and its activator being bound to fibrin.

Interaction
Subunit
Interacts with CSPG4 and AMOT. 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 ATP5F1A; the interaction inhibits most of the angiogenic effects of angiostatin.
