Comment |
FUNCTION:Catalyzes the transfer of sulfate to position 6 of non- reducing N-acetylglucosamine (GlcNAc) residues within mucin- associated glycans that ultimately serve as L-selectin ligands. L- selectin ligands are present in high endothelial cells (HEVs) and play a central role in lymphocyte homing at sites of inflammation. Participates in biosynthesis of L-selectin ligand sialyl 6-sulfo Lewis X on L-selectin counter receptors CD43, GlyCAM-1 and MAdCAM- 1. Also involved in biosynthesis of L-selectin ligand recognized by MECA-79 antibody. Plays a central role in lymphocyte trafficking during chronic inflammation. Has a catalytic preference for core 2-branched mucin-type O-glycans. Can use GlcNAcbeta1-6[Galbeta1-3]GalNAc-pNP (core 2), GlcNAcbeta1-6ManOMe and GlcNAcbeta1-2Man oligosaccharide structures as acceptors. Has also activity toward core 3 of GlcNAcbeta1-3GalNAc-pNP. Its substrate specificity may be influenced by its subcellular location.||SUBUNIT:Monomer.||SUBCELLULAR LOCATION:Go |
