Anti-ITM1 antibodies are protein reagents that detect specific antigens. The ITM1 antigen is another term for the human protein STT3 oligosaccharyltransferase complex catalytic subunit A, encoded by the STT3A gene. The protein is a known catalytic subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. Canonically, it has an amino acid length of 705 residues and a mass of 80.5 kilodaltons. Its subcellular localization is in the ER and it is notably expressed at high levels in the placenta, liver, muscle and pancreas, and at very low levels in the brain, lung and kidney. The ITM1 protein is a member of the STT3 protein family. Other alias names for ITM1 include CDG1WAD and CDG1WAR. Indicated applications for ITM1 antibodies listed below include ELISA and Immunohistochemistry.
