      Background InformationTAK1 binding protein 1 (TAB1) is thought to activate TAK1 MAPKKK in transforming growth factor-beta (TGF-beta) signaling. TAB1 can also associate with TAK1 to form a unique MAPKKK complex that is thought to activate AP-1 and the NFkappaB signaling pathways. Through conformational changes, TAB1 is also thought to induce p38alpha autophosphorylation. It has been linked to both IL-1alpha and TNFalpha signaling and therefore may also be involved in the inflammatory response. Recent research has found that the TAK1-TAB1 complex may have anti-inflammatory effects by aiding stercurensin in regulating the NFκB-dependent inflammatory pathways.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene was identified as a regulator of the MAP kinase kinase kinase MAP3K7/TAK1, which is known to mediate various intracellular signaling pathways, such as those induced by TGF beta, interleukin 1, and WNT-1. This protein interacts and thus activates TAK1 kinase. It has been shown that the C-terminal portion of this protein is sufficient for binding and activation of TAK1, while a portion of the N-terminus acts as a dominant-negative inhibitor of TGF beta, suggesting that this protein may function as a mediator between TGF beta receptors and TAK1. This protein can also interact with and activate the mitogen-activated protein kinase 14 (MAPK14/p38alpha), and thus represents an alternative activation pathway, in addition to the MAPKK pathways, which contributes to the biological responses of MAPK14 to various stimuli. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: May be an important signaling intermediate between TGFB receptors and MAP3K7/TAK1. May play an important role in mammalian embryogenesis.

      SUBUNIT STRUCTURE: Interacts with XIAP and BIRC7. Interacts with TRAF6 and MAP3K7; during IL-1 signaling. Identified in the TRIKA2 complex composed of MAP3K7, TAB1 and TAB2.

      TISSUE SPECIFICTY: Ubiquitous.

      PTM: Monoubiquitinated. Deubiquitinated by Y.enterocolitica YopP.

      SEQUENCE SIMILARITIES: Contains 1 PP2C-like domain.
      Molecular Weight ~72/58 kDa observed. ~56 kDa calculated. The observed kDa may be due to glycosylation. (Ohkusu-Tsukada, K., et al. (2010). Eur. J. Immunol. 40:1011–1021.) An uncharacterized band appears at ~30 kDa.
