The full-length crystal structure of Toxascaris leonine galectin (Tl-gal), a galectin-9 homologue protein, was determined at a resolution of 2.0 Å. The NCRD of Tl-gal resembles that of human galectin-7 and its CCRD resembles human galectin-9, but the residues in the interface and loop regions of the NCRD and CCRD are flexible and are related to interaction.
