This locus encodes a sulfotransferase protein. The encoded enzyme catalyzes the sulfation of a nonreducing N-acetylglucosamine residue, and may play a role in biosynthesis of 6-sulfosialyl Lewis X antigen.CHST2 (Carbohydrate Sulfotransferase 2) is a Protein Coding gene. Among its related pathways are Keratan sulfate/keratin metabolism and Glycosaminoglycan metabolism. GO annotations related to this gene include sulfotransferase activity and N-acetylglucosamine 6-O-sulfotransferase activity. An important paralog of this gene is CHST7.
