General annotation (Comments)

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 it weakens the walls of the Graafian follicle. It activates the urokinase-type plasminogen activator, collagenases and several complement zymogens, such as C1 and C5. It cleaves fibrin, fibronectin, thrombospondin, laminin and von Willebrand factor. Its role in tissue remodeling and tumor invasion may be modulated by CSPG4 By similarity.
Catalytic activity	Preferential cleavage: Lys-|-Xaa > Arg-|-Xaa; higher selectivity than trypsin. Converts fibrin into soluble products.
Enzyme regulation	Converted into plasmin by plasminogen activators, both plasminogen and its activator being bound to fibrin. Cannot be activated with streptokinase By similarity.
Subunit structure	Interacts with CSPG4 By similarity.
Subcellular location	Secreted.
Domain	Kringle domains mediate interaction with CSPG4 By similarity.
Miscellaneous	Plasmin is inactivated by alpha-2-antiplasmin immediately after dissociation from the clot By similarity.
Sequence similarities	Belongs to the peptidase S1 family. Plasminogen subfamily. Contains at least 1 kringle domain.
