RT   aggregation inhibitors from the leech Placobdella ornata.";
RL   Eur. J. Biochem. 202:1073-1082(1991).
CC   -!- FUNCTION: Potent inhibitor of fibrinogen interaction with platelet
CC       receptors expressed on glycoprotein IIb-IIIa complex. May prevent blood
CC       from clotting during either feeding and/or storage of ingested blood.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the ornatin family. {ECO:0000305}.
