Anti-protein O-glucosyltransferase 3 antibodies are used for the immunodetection of the protein encoded by the POGLUT3 gene. In humans, the canonical protein has a reported length of 507 amino acid residues and a mass of 58.6 kDa. Its subcellular localization is in the ER. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the KDELC protein family, it is reported to be a protein glucosyltransferase that catalyzes the transfer of glucose from UDP-glucose to a serine residue within the consensus sequence peptide C-X-N-T-X-G-S-F-X-C. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include KDEL motif containing 2, KDEL motif-containing protein 2, protein O-xylosyltransferase POGLUT3, and KDEL (Lys-Asp-Glu-Leu) containing 2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
