Function

ATLE_CYCAE Anti-tumor lectin with DNase activity. Inhibits the growth of several tumor cell lines in vitro. Induces lymphocyte infiltration and necrosis of tumor cells in a mouse tumor model. Induces apoptosis in HeLa cells. Binds N-acetylneuraminyl lactose (N-acetyl-alpha-neuraminyl-(2->3)-beta-D-galactosyl-(1->4)-beta-D-glucose) (PubMed:16051274).^[1] ^[2]
