Protein attributes

Sequence length	432 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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.
