  • Function

    Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Has activity toward HIV envelope glycoprotein gp120, EA2, Muc2 and Muc5. Probably glycosylates fibronectin in vivo. Glycosylates FGF23. Plays a central role in phosphate homeostasis.
  • Tissue specificity

    Expressed in organs that contain secretory epithelial glands. Highly expressed in pancreas, skin, kidney and testis. Weakly expressed in prostate, ovary, intestine and colon. Also expressed in placenta and lung and fetal lung and fetal kidney.
  • Pathway

    Protein modification; protein glycosylation.
  • Involvement in disease

    Defects in GALNT3 are a cause of hyperphosphatemic familial tumoral calcinosis (HFTC) [MIM:211900]. HFTC is a severe autosomal recessive metabolic disorder that manifests with hyperphosphatemia and massive calcium deposits in the skin and subcutaneous tissues. Some patients manifest recurrent, transient, painful swellings of the long bones associated with the radiographic findings of periosteal reaction and cortical hyperostosis and absence of skin involvement.
  • Sequence similarities

    Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
    Contains 1 ricin B-type lectin domain.
  • Domain

    There are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding.
    The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.
  • Cellular localization

    Golgi apparatus > Golgi stack membrane. Resides preferentially in the trans and medial parts of the Golgi stack.
