  • Background Information
    Polypeptide N-acetylgalactosaminyltransferase 3 (GalNAc-T3) catalyzes the transfer of N-acetylgalactosamine (GalNAc) from UDP-GalNAc to the hydroxyl group of serine and threonine residues. Twenty GalNAc-T genes have been identified in humans and most have been shown to represent active GalNAc-Ts. All isoforms are type II transmembrane proteins, with different but partly overlapping substrate preferences. The GalNAc-Ts control the initiation of mucin-type O-linked glycosylation and determine the location and density of O-glycans in a protein. Addition of GalNAc to an unglycosylated Ser/Thr residue creates the Tn antigen GalNAcα1-S/T, and subsequent addition of sialic acid by ST6GalNAc-I forms the cancer associated STn antigen. GalNAc-T3 is highly expressed in pancreas and testis, and weakly expressed in a few other organs such as placenta. The expression levels of GalNAc-T3 were found to be upregulated in highly differentiated types of adenocarcinoma cell lines as opposed to less differentiated types. Overexpression of GalNAc-T3 has also been found to promote pancreatic cancer cell growth. Mutations in GalNAc-T3 were found to be involved in familial tumoral calcinosis, which may be mediated through glycosylation of fibroblast growth factor 23, protecting it from proteolytic cleavage. GalNAc-T3 has a preference for mono- or diglycosylated substrates.
  • Handling

  • Usage
    For Research Use Only! Not to be used in humans
  • Properties
    Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.

  • Short name
    GalNAc-T3, soluble , Recombinant
  • Technique
    Recombinant, E. coli recombinant proteins are genetic recombinations in Escherichia coli, supplied as white sterile powder lyopillized. Biovision advises they will be reconstituted in a buffer soluion or culture medium for cell culture.
  • Isotype
    Antibody fragments and scFv fragments, single chain variable fragments can be E. coli expressed. Fragment peptides for polyclonals give monoclonal like antibodies as the epitope is very small. IgG Fc and(ab)2 fragments are small and stable subunits of the antibody obtained by enzymatic digestion. Complement fragments, bp DNA fragments are common.
