RT   "Molecular cloning and characterization of UDP-GlcNAc:lactosylceramide beta

RT   the expression of HNK-1 and Lewis X epitopes on glycolipids.";
RL   J. Biol. Chem. 276:22032-22040(2001).
CC   -!- FUNCTION: Beta-1,3-N-acetylglucosaminyltransferase that plays a key
CC       role in the synthesis of lacto- or neolacto-series carbohydrate chains
CC       on glycolipids, notably by participating in biosynthesis of HNK-1 and
CC       Lewis X carbohydrate structures. Has strong activity toward
CC       lactosylceramide (LacCer) and neolactotetraosylceramide (nLc(4)Cer;
CC       paragloboside), resulting in the synthesis of Lc(3)Cer and
CC       neolactopentaosylceramide (nLc(5)Cer), respectively. Probably plays a
CC       central role in regulating neolacto-series glycolipid synthesis during
CC       embryonic development. {ECO:0000250|UniProtKB:Q9BYG0}.
