CC   -!- FUNCTION: Sulfotransferase involved in SELL/L-selectin ligand
CC       biosynthesis pathway. Catalyzes the transfer of the sulfate group from
CC       3'-phospho-5'-adenylyl sulfate (PAPS) onto the hydroxyl group at C-6
CC       position of the non-reducing N-acetylglucosamine (GlcNAc) residue
CC       within O-linked mucin-type glycans. Contributes to generate sialyl 6-
CC       sulfo Lewis X determinant (also known as MECA-79 epitope) for SELL
CC       recognition, a prerequisite for continuous lymphocyte homing into
CC       peripheral lymph nodes and antigen immune surveillance
CC       (PubMed:11439191, PubMed:12107080, PubMed:10330415, PubMed:11726653).
CC       Transfers the sulfate group primarily on core 2 GlcNAcbeta1-6(Galbeta1-
CC       3)GalNAcalphaSer/Thr and extended core 1 GlcNAcbeta1-3Galbeta1-
CC       3GalNAcalphaSer/Thr based O-linked glycans on CD34 and GLYCAM1
CC       peripheral node addressins (PNAds) expressed on the lumenal side of
CC       high endothelial venules (HEVs) (PubMed:11439191). The recognition of
CC       PNAds by SELL initiates a multistep process comprising tethering and
CC       rolling of blood lymphocytes on HEVs against the blood flow, followed
CC       by chemokine signaling, integrin-mediated lymphocyte adhesion onto
CC       endothelial cells and lymphocyte transendothelial migration. Modulates
CC       rolling velocity and differential T and B lymphocyte recruitment into
CC       peripheral lymph nodes, with a major role in B lymphocyte homing. Might
CC       be redundant in sulfation of MADCAM1 and lymphocyte trafficking to
CC       mesenteric lymph nodes (By similarity). Can also sulfonate core 3
CC       GlcNAcbeta1-3GalNAc-R based glycans as well as GlcNAcbeta1-3Galbeta1-
CC       Glc, GlcNAcbeta1-6ManOMe and GlcNAcbeta1-2Man oligosaccharides, which
CC       might be ectopically expressed during tumorigenesis (PubMed:12107080,
