RT "Molecular cloning and characterization of UDP-GlcNAc:lactosylceramide beta
RT 1,3-N-acetylglucosaminyltransferase (beta 3Gn-T5), an essential enzyme for
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}.

CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000250}; Single-
CC pass type II membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 31 family.
