  • Function
    It may be responsible for the synthesis of the sequence NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc- found on sugar chains O-linked to Thr or Ser and also as a terminal sequence on certain gangliosides. SIAT4A and SIAT4B sialylate the same acceptor substrates but exhibit different Km values.
  • Tissue specificity
    Expressed in several tissues. Highest expression in lung, liver, skeletal muscle, kidney, pancreas, spleen and placenta.
  • Pathway
    Protein modification; protein glycosylation.
  • Sequence similarities
    Belongs to the glycosyltransferase 29 family.
  • Post-translational
    The soluble form derives from the membrane form by proteolytic processing.
  • Cellular localization
    Golgi apparatus > Golgi stack membrane. Secreted. Membrane-bound form in trans cisternae of Golgi. Secreted into the body fluid.

Thank you for your enquiry. I can confirm that the protein database links on the datasheet (SwissProt and Unigene) indicate that SIAT4A is expressed in pancreas. However, I am sorry I have done a literature search and I am not able to confirm t...
