ID:TAB3_HUMAN DESCRIPTION: RecName: Full=TGF-beta-activated kinase 1 and MAP3K7-binding protein 3; AltName: Full=Mitogen-activated protein kinase kinase kinase 7-interacting protein 3; AltName: Full=NF-kappa-B-activating protein 1; AltName: Full=TAK1-binding protein 3; Short=TAB-3; AltName: Full=TGF-beta-activated kinase 1-binding protein 3; FUNCTION: Adapter linking MAP3K7/TAK1 and TRAF6 or TRAF2. Mediator of MAP3K7 activation, respectively in the IL1 and TNF signaling pathways. Plays a role in activation of NF-kappa-B and AP1 transcription factor. Isoform 2 may be an oncogenic factor. SUBUNIT: Interacts with TAB1, TAB2, MAP3K7, TRAF2 and TRAF6. The minimal TAB3-containing complex (TAB1-MAP3K7-TAB3) appears not to contain TAB2. However, it seems sensible to consider that TAB2 may also join this complex and may act in a cooperative manner with TAB3. Interacts with WDR34 (via the WD domains). Interacts with RBCK1. Binds 'Lys-63'-linked polyubiquitin chains. INTERACTION: Q62073:Map3k7 (xeno); NbExp=2; IntAct=EBI-359964, EBI-1775345; TISSUE SPECIFICITY: Widely expressed. Constitutively overexpressed in certain tumor tissues. Isoform 1 is a major transcript while isoform 2 is a minor transcript. DOMAIN: The RanBP2-type zinc finger (NZF) mediates binding to two consecutive 'Lys-63'-linked ubiquitins (By similarity). PTM: Ubiquitinated; following IL1 stimulation or TRAF6 overexpression. PTM: Phosphorylated at Ser-506 by MAPKAPK2 and MAPKAPK3 following IL1 treatment. SIMILARITY: Contains 1 CUE domain. SIMILARITY: Contains 1 RanBP2-type zinc finger.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
