FunctionATLE_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] Publication Abstract from PubMedA fungal galectin from Agrocybe cylindracea (ACG) exhibits broad binding specificity for beta-galactose-containing glycans. We determined the crystal structures of wild-type ACG and the N46A mutant, with and without glycan ligands. From these structures and a saccharide-binding analysis of the N46A mutant, we revealed that a conformational change of a unique insertion sequence containing Asn46 provides two binding modes for ACG, and thereby confers broad binding specificity. We propose that the unique sequence provides these two distinct glycan-binding modes by an induced-fit mechanism. Conformational change of a unique sequence in a fungal galectin from Agrocybe cylindracea controls glycan ligand-binding specificity.,Kuwabara N, Hu D, Tateno H, Makyio H, Hirabayashi J, Kato R FEBS Lett. 2013 Nov 15;587(22):3620-5. doi: 10.1016/j.febslet.2013.08.046.
