Anti-TAB2 antibodies are used in the immunodetection of the protein TGF-beta activated kinase 1 (MAP3K7) binding protein 2. In humans, the canonical protein has a reported length of 693 amino acid residues and a mass of 76.5 kDa. Its subcellular localization is in the membrane, lysosomes and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is widely expressed across many tissue types. Among its functions, TAB2 is involved with cardiac tissue development and autophagy pathways. Post-translational modifications have been described, including methylation, ubiquitination and phosphorylation. Synonyms for this target antigen include MAP3K7IP2, TGF-beta-activated kinase 1 and MAP3K7-binding protein 2, TAK1-binding protein 2, mitogen-activated protein kinase kinase kinase 7-interacting protein 2, and CHTD2.
