General description
Plasmin functions as a key enzyme of the fibrinolytic cascade, and is also important in inflammation processes.
Application
A complex between plasmin and an inhibitor has been isolated in a study via affinity chromatography from urokinase-activated human plasma. It has also been used in a study to investigate activation of human epithelial sodium channel (ENaC) by plasmin and chymotrypsin.
Biochem/physiol Actions
It is inhibited by α 2-antiplasmin and its interaction with fibrin is blocked. It digests the N-terminal region of the cytoplasmic protein αsynuclein preventing its uptake by surrounding cells.
Plasmin exhibits preferential cleavage at the carboxyl side of lysine and arginine residues with higher selectivity than trypsin. Converts polymerized fibrin into soluble products.

A complex between plasmin and an inhibitor was isolated by affinity chromatography from urokinase-activated human plasma. The complex did not react with antibodies against any of the known proteinase inhibitors in plasma. A rabbit antiserum against the complex was produced.

The serine protease plasmin generated from its zymogen plasminogen is best known for its function as a key enzyme of the fibrinolytic cascade. However, beyond fibrinolysis, plasmin has a number of crucial functions in a variety of processes, including inflammation.
