Common Name | 6-Sialyl-N-acetyllactosamine |
---|
Description | 6-Sialyl-N-acetyllactosamine is an oligosaccharide widely distributed among tissues and is involved in biological processes such as the regulation of the immune response and the progression of colon cancer. Sialylation represents one of the most frequently occurring terminations of the oligosaccharide chains of glycoproteins and glycolipids. Sialic acid is commonly found alpha,3- or alpha,6-linked to galactose (Gal), alpha,6-linked to N-acetylgalactosamine (GalNAc) or alpha,8-linked to another sialic acid. The biosynthesis of the various linkages is mediated by the different members of the sialyltransferase family. The b-galactoside a2,6 sialyltransferase (EC 2.4.99.1, ST6Gal.I) is the only sialyltransferase so far identified able to catalyze the a2,6-sialylation of lactosamine. Although expressed by a single gene, this enzyme shows a complex pattern of regulation which allows its tissue- and stage-specific modulation. The level of expression of the sialyl-alpha2,6-lactosaminyl structures and of ST6Gal.I show a strong dependence on neoplastic transformation and differentiation in several tissues.
