Summaries for GALNT3 Gene

Entrez Gene Summary for GALNT3 Gene

  • This gene encodes UDP-GalNAc transferase 3, a member of the GalNAc-transferases family. This family transfers an N-acetyl galactosamine to the hydroxyl group of a serine or threonine residue in the first step of O-linked oligosaccharide biosynthesis. Individual GalNAc-transferases have distinct activities and initiation of O-glycosylation is regulated by a repertoire of GalNAc-transferases. The protein encoded by this gene is highly homologous to other family members, however the enzymes have different substrate specificities. [provided by RefSeq, Jul 2008]

GeneCards Summary for GALNT3 Gene

GALNT3 (Polypeptide N-Acetylgalactosaminyltransferase 3) is a Protein Coding gene. Diseases associated with GALNT3 include hyperphosphatemic familial tumoral calcinosis, galnt3-related and tumoral calcinosis, hyperphosphatemic, familial. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include calcium ion binding and polypeptide N-acetylgalactosaminyltransferase activity. An important paralog of this gene is GALNT4.

UniProtKB/Swiss-Prot for GALNT3 Gene

  • 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.

Q14435

UniProtKB/Swiss-Prot:

GALT3_HUMAN :
  • Q14435
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.
  • Contains 1 ricin B-type lectin domain.
Family:
  • Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
