  6. N-acetylgalactosaminyltransferase 1
Gene Name CHSY1
Protein Type Enzyme
Biological Properties
General Function Involved in transferase activity, transferring hexosyl groups
Specific Function Has both beta-1,3-glucuronic acid and beta-1,4-N-acetylgalactosamine transferase activity. Transfers glucuronic acid (GlcUA) from UDP-GlcUA and N-acetylgalactosamine (GalNAc) from UDP-GalNAc to the non-reducing end of the elongating chondroitin polymer. Involved in the negative control of osteogenesis likely through the modulation of NOTCH signaling.
