Anti-GALNT11 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 11. In humans, the canonical protein has a reported length of 608 amino acid residues and a mass of 68.9 kDa. Its subcellular localization is in the Golgi. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the kidney. A member of the Glycosyltransferase 2 protein family, GALNT11 is reported to be a Polypeptide N-acetylgalactosaminyltransferase that catalyzes the initiation of protein O-linked glycosylation and is involved in left/right asymmetry by mediating O-glycosylation of NOTCH1. Synonyms for this target antigen include UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 11 (GalNAc-T11), polypeptide GalNAc transferase 11, pp-GaNTase 11, and UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 11. GALNT11 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for GALNT11 antibodies.
