CC -!- FUNCTION: Galactose (Gal) transferase involved in the synthesis of
CC terminal N-acetyllactosamine (LacNac) unit present on glycan chains of
CC glycoproteins and glycosphingolipids. Catalyzes the transfer of Gal
CC residue via a beta1->4 linkage from UDP-Gal to the non-reducing
CC terminal N-acetyl glucosamine 6-O-sulfate (6-O-sulfoGlcNAc) in the
CC linearly growing chain of both N- and O-linked keratan sulfate
CC proteoglycans. Cooperates with B3GNT7 N-acetyl glucosamine transferase
CC and CHST6 and CHST1 sulfotransferases to construct and elongate
CC mono- and disulfated disaccharide units [->3Galbeta1->4(6-
CC sulfoGlcNAcbeta)1->] and [->3(6-sulfoGalbeta)1->4(6-
CC sulfoGlcNAcbeta)1->] within keratan sulfate polymer. Transfers Gal
CC residue via a beta1->4 linkage to terminal 6-O-sulfoGlcNAc within the
CC LacNac unit of core 2 O-glycans forming 6-sulfo-sialyl-Lewis X (sLex).
CC May contribute to the generation of sLex epitope on mucin-type
CC glycoproteins that serve as ligands for SELL/L-selectin, a major
CC regulator of leukocyte migration. In the biosynthesis pathway of
CC neolacto-series glycosphingolipids, transfers Gal residue via a
CC beta1->4 linkage to terminal GlcNAc of a lactotriaosylceramide (Lc3Cer)
CC acceptor to form a neolactotetraosylceramide.
