  • Function
    Involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on glycoproteins. Can also play a role in glycosaminoglycan biosynthesis. Substrates include asialo-orosomucoid (ASOR), asialo-fetuin, and asialo-neural cell adhesion molecule. Requires sphingomyelin for activity: stearoyl-sphingomyelin was the most effective, followed by palmitoyl-sphingomyelin and lignoceroyl-sphingomyelin. Activity was demonstrated only for sphingomyelin with a saturated fatty acid and not for that with an unsaturated fatty acid, regardless of the length of the acyl group.
  • Tissue specificity
    Mainly expressed in the brain.
  • Pathway
    Protein modification; protein glycosylation.
  • Sequence similarities
    Belongs to the glycosyltransferase 43 family.
  • Cellular localization
    Golgi apparatus membrane.
