GALNT3

Gene
GALNT3
Protein
Polypeptide N-acetylgalactosaminyltransferase 3
Organism
Homo sapiens
Length
633 amino acids
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.
Similarity
Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
