    basic FUNCTION
  • exhibits strong activity to transfer GlcNAc to glycolipid substrates and is the most likely candidate for lactotriaosylceramide synthase
  • may be playing a role in regulating neolacto-series glycolipid synthesis during embryonic development
  • is essential for the expression of Lewis X epitopes on glycolipids
