PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • sialyl motifs L, S, and VS, (L and S previously demonstrated their involvement in the binding of donor and acceptor substrates)
  • region comprised between the sialyl motifs S and VS contains a stretch of four highly conserved residues, with the following consensus sequence (H/y)Y(Y/F/W/h)(E/D/q/g)
  • four N-glycan attachment sites in its catalytic domain that are potentially glycosylated (N-glycosylation appears to contribute to the proper folding and trafficking of the enzyme)
  • conjugated GlycoP
    isoforms Precursor the soluble form derives from the transmembrane form by proteolytic processing

    text
  • type II membrane protein
  • membrane-bound form in tran-cisternae of Golgi
  • soluble form in body fluids
  • basic FUNCTION
  • transfering sialic acid to terminal positions on the carbohydrate groups of glycoproteins and glycolipids
  • being key determinants for a variety of cellular recognition processes
  • sialyltransferase involved in the biosynthesis of sialyl-Lewis epitopes on cell surface-expressed glycoproteins
  • CELLULAR PROCESS protein, post translation

    REGULATION
    Other regulated by all-trans-retinoic acid (RA) (RA is a significant regulator of GALM and other galactose-related genes in myeloid-monocytic cells, which could affect energy utilization and synthesis of cell-surface glycoproteins or glycolipids involved in cell motility, adhesion, and/or functional properties)
