Uniprot Id

Q9Y2A9

Target Species

Human

Target Name

B3GNT3

Target Full Name

N-acetyllactosaminide beta-1,3-N-acetylglucosaminyltransferase 3

Target Function

Beta-1,3-N-acetylglucosaminyltransferase involved in the synthesis of poly-N-acetyllactosamine. Has activity for type 2 oligosaccharides. Also acts as a core1-1,3-N-acetylglucosaminyltransferase (Core1-beta3GlcNAcT) to form the 6-sulfo sialyl Lewis x on extended core1 O-glycans.

Target Subcellular Location

Golgi apparatus membrane; Single-pass type II membrane protein.

Target Protein Families

Glycosyltransferase 31 family

Target Tissue Specificity

Expressed in colon, jejunum, stomach, esophagus, placenta and trachea.

Target Background

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.
