Engineered intrinsically fluorescent galectin-8 variants with altered valency, ligand recognition and biological activity.

Galectin-8 is a small soluble lectin with two carbohydrate recognition domains (CRDs). N- and C-terminal CRDs of Gal-8 differ in their specificity for glycan ligands. Here, we wanted to find out whether oligomerization of individual CRDs of galectin-8 affects its biological activity.
