General annotation (Comments)

Function

Specifically cleave the zymogen plasminogen to form the active enzyme plasmin.

Catalytic activity

Specific cleavage of Arg-|-Val bond in plasminogen to form plasmin.

Subunit structure

Found in high and low molecular mass forms. Each consists of two chains, A and B. The high molecular mass form contains a long chain A which is cleaved to yield a short chain A. Binds LRP1B; binding is followed by internalization and degradation. Interacts with MRC2. Interacts with PLAUR By similarity.

Subcellular location

Secreted By similarity.

Sequence similarities

Belongs to the peptidase S1 family.

Contains 1 EGF-like domain.

Contains 1 kringle domain.

Contains 1 peptidase S1 domain.
