Human GALNT3, recombinant (C-6His)

Recombinant Human Polypeptide N-acetylgalactosaminyltransferase 3 is produced by our Mammalian expression system and the target gene encoding Gln38-Asp633 is expressed with a 6His tag at the C-terminus. Protein 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.
