Characterization of the galectin-1 carbohydrate recognition domain in terms of solvent occupancy

Human galectin-1, a galactosil-terminal sugar binding soluble protein, is a potent multifunctional effector that participates in specific protein-carbohydrate and protein-protein interactions. Recent studies revealed that it plays a key role as a modulator of cellular differentiation and immunologic...
