CC -!- FUNCTION: Probably essential to support the feeding habits of this
CC exclusively haematophagous animal. Potent thrombolytic agent.
CC -!- CATALYTIC ACTIVITY: Specific cleavage of Arg-|-Val bond in
CC plasminogen to form plasmin.
CC -!- ENZYME REGULATION: Activity toward plasminogen is stimulated in
CC the presence of fibrin I.
CC -!- SUBUNIT: Monomer.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- DOMAIN: The fibronectin type-I domain mediates binding to fibrin,
CC and the kringle domain apparently mediates fibrin-induced
CC stimulation of activity.
CC -!- SIMILARITY: Belongs to the peptidase S1 family.
CC -!- SIMILARITY: Contains 1 EGF-like domain.
CC -!- SIMILARITY: Contains 1 fibronectin type-I domain.
CC -!- SIMILARITY: Contains 1 kringle domain.
CC -!- SIMILARITY: Contains 1 peptidase S1 domain.
