Function |
Converts the abundant, but inactive, zymogen plasminogen to plasmin by hydrolyzing a single Arg-Val bond in plasminogen. By controlling plasmin-mediated proteolysis, it plays an important role in tissue remodeling and degradation, in cell migration and many other physiopathological events. During oocyte activation, plays a role in cortical granule reaction in the zona reaction, which contributes to the block to polyspermy.

- Data suggest that protein aggregates interact with tissue-type plasminogen activator and plasminogen to efficiently generate plasmin; this aggregate-bound plasmin is shielded from inhibition by alpha-2-antiplasmin and degrades protein aggregates to release smaller, soluble but relatively hydrophobic peptide fragments; these fragments bind to and are cytotoxic to microglia (by not vascular endothelial cells).
