CD BioGlyco is a world-leading independent biotechnology company, focusing on high-quality innovative services related to glycobiology. We aim to provide customers with unparalleled support services for glycomedicine development based on targeting carbohydrate-lectin interactions.
Lectins are proteins which bind to carbohydrate and must be neither of immune origin (e. g. not antibodies) nor catalytic (e. g. not enzymes). Carbohydrate recognition systems have been described as a functional triad of lectin, carrier (protein, peptide, or lipid), and carbohydrate. There are two categories of lectins present in vertebrates: the families of intracellular lectins (for example, calnexin, L-type and P-type lectins), which bind core oligosaccharide structures and are involved in glycoprotein processing and quality control, and the families of extracellular lectins (for example, galectins, C-type, I-type and R-type lectins), which recognize terminal carbohydrate epitopes of other cells and pathogens. Extracellular lectins account for most of the molecular targets that are being investigated in current drug discovery programs. Glycan–lectin interactions mediate many different biological processes, including cell-cell recognition, developmental processes, and protection against pathogens. Even small changes in carbohydrate moieties may strongly affect interaction and consequent functionality
Great strides have been made with respect to the ligand binding specificities and molecular structures of the five families of mammalian lectins. A rational pattern of ligand discrimination emerges based upon the three-dimensional orientation of binding site amino acid residues, specific ligand tissue distribution, and lectin regulation to exhibit or lack binding activity under different cellular conditions. Lectins bind monosaccharides and monovalent ligands with low affinity while binding multimeric ligands and ligand-carrier complexes with high avidity. Glycan recognition by lectins is intimately involved in many aspects of cell physiology. Therefore, the development of glycomedicine based on targeting carbohydrate-lectin interactions can provide more ideas.
