== Function Summary ==
* **Entrez Summary**: This gene encodes a member of the beta-1,3-N-acetylglucosaminyltransferase family. This enzyme is a type II transmembrane protein and contains a signal anchor that is not cleaved. It prefers the substrates of lacto-N-tetraose and lacto-N-neotetraose, and is involved in the biosynthesis of poly-N-acetyllactosamine chains and the biosynthesis of the backbone structure of dimeric sialyl Lewis a. It plays dominant roles in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. [provided by RefSeq, Jul 2008].
* **UniProt Summary**: Beta-1,3-N-acetylglucosaminyltransferase involved in the synthesis of poly-N-acetyllactosamine. Has activity for type 2 oligosaccharides (PubMed:11042166). Also acts as a core1-1,3-N- acetylglucosaminyltransferase (Core1-beta3GlcNAcT) to form the 6- sulfo sialyl Lewis x on extended core1 O-glycans (PubMed:11439191). {ECO:0000269|PubMed:11042166, ECO:0000269|PubMed:11439191}.
