GALNT9 (Polypeptide N-acetylgalactosaminyltransferase 9, Polypeptide GalNAc Transferase 9, GalNAc-T9, pp-GaNTase 9, Protein-UDP Acetylgalactosaminyltransferase 9, UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 9)

GALNT9 belongs to the glycosyltransferase 2 family, GalNAc-T subfamily and contains 1 ricin B-type lectin 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. It is specifically expressed in brain. Not expressed in heart, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, testis, ovary, small intestine, colon and leukocyte. In brain, it is expressed in cerebellum, frontal lobe, temporal lobe, putamen and spinal cord, weakly expressed in cerebral cortex. Not expressed in medulla and occipital pole. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity. GALNT9 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. It does not glycosylate apomucin or SDC3.\n\nApplications:\nSuitable for use in Western Blot.
