Glucose and N-acetylglucosamine binding lectin. Has hemagglutinating activity against human and rabbit erythrocytes which does not require divalent cations. Inhibits factor Xa and, to a lesser extent, trypsin. Does not inhibit neutrophil elastase, human plasma kallikrein, papain, human plasmin, porcine pancreatic kallikrein and bovin chymotrypsin. Has insecticidal activity against the termite species N.corniger. Induces apoptosis in prostrate cancer cell lines DU145 and PC3. Hemagglutinating activity is stable between 30 and 60 degrees Celsius. Dimer. LD(50) is 0.45 mg/ml against the termite species N.corniger. Belongs to the protease inhibitor I3 (leguminous Kunitz-type inhibitor) family. Characterization did not differentiate between the two isoforms determined by protein sequencing (PubMed:22195573, PubMed:23823708).
