Critical role of the solvent environment in galectin-1 binding to the disaccharide lactose

Galectin-1 (Gal-1), a member of a family of evolutionarily conserved glycan-binding proteins, binds specifically to poly-N-acetyllactosamine-enriched glycoconjugates. Through interactions with these glycoconjugates, this protein modulates inflammatory responses and contributes to tumor progression a...
