Anti-Transglutaminase 1 antibodies are used for the immunodetection of the protein encoded by the TGM1 gene. In humans, the canonical protein has a reported length of 817 amino acid residues and a mass of 89.8 kDa. Its subcellular localization is in the membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Transglutaminase protein family, it is known to catalyze the cross-linking of proteins and the conjugation of polyamines to proteins. Post-translational modifications have been described, including palmitoylation, protein cleavage and phosphorylation. Other names for this target antigen include ICR2, KTG, LI, LI1, TGASE, TGK, protein-glutamine gamma-glutamyltransferase K, and ARCI1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of Transglutaminase 1 antibodies have been mentioned in research publications and have associated citations. Western Blot and Immunohistochemistry are common applications for these antibodies.
