CC -!- FUNCTION: Probably essential to support the feeding habits of this
CC exclusively haematophagous animal. Potent thrombolytic agent.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Specific cleavage of Arg-|-Val bond in plasminogen to form
CC plasmin.; EC=3.4.21.68;
CC -!- ACTIVITY REGULATION: Activity toward plasminogen is stimulated in the
CC presence of fibrin I.
CC -!- SUBUNIT: Monomer.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- DOMAIN: The fibronectin type-I domain mediates binding to fibrin, and
CC the kringle domain apparently mediates fibrin-induced stimulation of
CC activity.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
