CHST6 polyclonal antibody

Sulfotransferase enzymes catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs and xenobiotic compounds. These enzymes differ in their tissue distributions and substrate specificities, although the gene structure (number and length of exons) is similar among family members. Carbohydrate sulfotransferase 5 (CHST5) (also referred to as GlcNAc6ST-3 or IGn6ST) and carbohydrate sulfotransferase 6 (CHST6) (also referred to as GlcNAc6ST-5 or Cgn6ST) are predominantly expressed in the intestine and cornea, respectively. They are highly homologous and both are orthologs of the murine CHST5. CHST5 and CHST6 may be the result of gene duplication. They catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine (GlcNAc) residues. CHST5 preferably mediates the sulfation of short carbohydrates and O-linked sugars of mucin-type acceptors. CHST6 mediates the sulfation of keratan in the cornea, which is important in maintaining corneal transparency.
