== Publication Abstract from PubMed ==
 +
Galectin-8 is a tandem-repeat-type beta-galactoside-specific animal lectin having N- and C-terminal carbohydrate recognition domains (N-CRD and C-CRD, respectively) with a difference in carbohydrate-binding specificity, involved in cell-matrix interaction, malignant transformation, and cell adhesion. N-CRD exhibits strong affinity for alpha2-3 sialylated oligosaccharides, a feature unique to galectin-8. C-CRD usually exhibits relatively lower affinity for oligosaccharides, but has higher affinity for N-glycan-type branched oligosaccharides than does N-CRD. There have been many structural studies on galectins with a single CRD, but no X-ray structure of a galectin containing both CRDs has been reported. Here, the X-ray structure of a protease-resistant mutant form of human galectin-8 having both CRDs and the novel pseudo-dimer structure of galectin-8 N-CRD in complexes with alpha2-3 sialylated oligosaccharide ligands were determined. The results revealed a difference in specificity between the N- and C-CRDs, and provided new insights into the association of CRDs and/or molecules of galectin-8.
