Plasmin is a major fibrinolytic protease with wide substrate specificity.
Plasminogen, a circulating plasma zymogen, can be converted to Plasmin by tissue-type Plasminogen activator ( PLAT ), Plasminogen activator urokinase ( PLAU ), Coagulation factor XII, or Kallikrein B plasma ( Plasma kallikrein ) .
Plasmin directly degrades Fibrinogen, Laminin, and Fibronectin. On the cell surface Plasmin activates a number of Metalloproteinases ( MMPs )  that degrade extracellular matrix proteins and components of basal membrane, such as Collagen, and Fibrinogen, which leads to thrombolysis.
Plasmin can activate or release from extracellular matrix a number of growth factors: Vascular endothelial growth factor ( VEGF ), Transforming growth beta ( TGF-beta ), or Fibroblast growth factor ( FGF2 ) . These growth factors bind to their receptors on the cell surface and activate intracellular signaling pathways that regulate cellular behavior. VEGF directly activates Phosphatidylinositol-3-kinase ( PI3K ) and V-akt murine thymoma viral oncogene homolog 1 ( AKT(PKB) ) signaling pathways. TGF-beta activates Mitogen activated protein kinase p38 signaling pathway via adaptor protein X-linked inhibitor of apoptosis ( XIAP ), Mitogen-activated protein kinase kinase kinase 7 interacting protein 1 ( TAB1 ) and Mitogen-activated protein kinase kinase kinase 7 ( TAK1 ) kinase.
Plasmin is also able to cleave TGF-beta receptor type III extracellular domain, suggesting possibility of yet another type of regulation of the receptor .
Plasmin is inhibited by Serpin peptidase inhibitor clade I member 1 ( Neuroserpin ), Serpin peptidase inhibitor clade G (C1 inhibitor) member 1 ( C1 inhibitor ), T issue factor pathway inhibitor 2 ( TFPI-2 ), Pregnancy zone protein ( PZP ), and Serine protease inhibitor serine peptidase inhibitor Kazal type 5 ( LEKTI ).
