Subcellular location

Subcellular Location:
Secreted, extracellular space.

Function

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. Plays a direct role in facilitating neuronal migration.
Catalytic Activity:
Specific cleavage of Arg-|-Val bond in plasminogen to form plasmin.
Enzyme Regulation:
ENZYME REGULATION: Inhibited by SERPINA5.
Active Site:
ACT_SITE 357 357 Charge relay system.; ACT_SITE 406 406 Charge relay system.; ACT_SITE 513 513 Charge relay system.
