Protein attributes

Sequence length	433 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript 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.
Induction	By retinoic acid.
Sequence similarities	Belongs to the peptidase S1 family. Contains 1 EGF-like domain. Contains 1 kringle domain. Contains 1 peptidase S1 domain.
