Carbohydrate Sulfotransferase 7/CHST7: Products

The CHST family is comprised of 14 genes in both human and mouse. All members of this family are Golgi-localized type II membrane proteins. Only the luminal and enzymatic domain is expressed in each of our recombinant CHST proteins. These enzymes transfer sulfate (i.e., sulfonate) onto the 6-O or 4-O positions of GalNAc, Gal and GlcNAc residues on glycoproteins, proteoglycans and glycolipids. This sulfation often creates specific epitopes that can be recognized by extracellular matrix proteins, cell surface receptors and viruses. CHST7, also designated as chondroitin 6-O-sulfotransferase (C6ST-2), N-acetylglucosamine-6-O-sulfotransferase (GlcNAc6ST-4) and Gal/GalNAc/GlcNAc 6-O-sulfotransferase (GST-5), was previously shown to act on chondroitin sulfate, mannose-linked GlcNAc and mucin associated GlcNAc residues. The amino acid sequence of mouse CHST7 is 87% identical to that of the human counterpart.
