Anti-TGM3 antibodies are used in the immunodetection of the protein transglutaminase 3. In humans, the canonical protein has a reported length of 693 amino acid residues and a mass of 76.6 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the esophagus and testis. A member of the Transglutaminase protein family, TGM3 is known to catalyze the calcium-dependent formation of isopeptide cross-links between glutamine and lysine residues in various proteins, as well as the conjugation of polyamines to proteins. Synonyms for this target antigen include UHS2, protein-glutamine gamma-glutamyltransferase E, E polypeptide, protein-glutamine-gamma-glutamyltransferase, TG(E), TGase E, and TGE. TGM3 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of TGM3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
