Previous GeneCards Identifiers 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 Tumoral Calcinosis, Hyperphosphatemic, Familial, 1 and Hyperphosphatemia. Among its related pathways are Mucin type O-glycan biosynthesis and O-linked glycosylation. Gene Ontology (GO) annotations related to this gene include calcium ion binding and transferase activity, transferring glycosyl groups. An important paralog of this gene is GALNT6.
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.
