Anti-TAB1 antibodies are used in the immunodetection of the protein TGF-beta activated kinase 1 (MAP3K7) binding protein 1. In humans, the canonical protein has a reported length of 504 amino acid residues and a mass of 54.6 kDa. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. TAB1 is believed to be an important signaling intermediate between TGFB receptors and MAP3K7/TAK1. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include MAP3K7IP1, TGF-beta-activated kinase 1 and MAP3K7-binding protein 1, TAK1-binding protein 1, mitogen-activated protein kinase kinase kinase 7-interacting protein 1, and 3'-Tab1. TAB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of TAB1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
