Anti-TAB3 antibodies are used in the immunodetection of the protein TGF-beta activated kinase 1 (MAP3K7) binding protein 3. In humans, the canonical protein has a reported length of 712 amino acid residues and a mass of 78.7 kDa. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. TAB3 is known to be involved with autophagy pathways and NF-kappaB signaling pathways. Post-translational modifications have been described, including methylation, ubiquitination and phosphorylation. Synonyms for this target antigen include NF-kappa-B-activating protein 1, NFkB activating protein 1, TAK1-binding protein 3, TGF-beta activated kinase 1 and MAP3K7 binding protein 3, and TGF-beta-activated kinase 1 and MAP3K7-binding protein 3. TAB3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of TAB3 antibodies have been mentioned in research publications and have associated citations. ELISA is a widely used application for these antibodies. Western Blot and Immunohistochemistry are also common applications.
