Anti-TRAF1 antibodies are used in the immunodetection of the protein TNF receptor associated factor 1. In humans, the canonical protein has a reported length of 416 amino acid residues and a mass of 46.2 kDa. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the skin, nasopharynx, lymph node, bone marrow, and appendix. TRAF1 is reported to be an adapter molecule that regulates the activation of NF-kappa-B and JNK. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include MGC:10353, Epstein-Bar virus-induced protein 6, and EBI6. TRAF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 110 citations in the literature describe the use of TRAF1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
