Gene Name TAB2
Protein Name TGF-beta-activated kinase 1/MAP3K7-binding protein 2
Molecular Weight 76494 MW
Protein Function Adapter linking MAP3K7/TAK1 and TRAF6. Promotes MAP3K7 activation in the IL1 signaling pathway. The binding of 'Lys-63'- linked polyubiquitin chains to TAB2 promotes autophosphorylation of MAP3K7 at 'Thr-187'. Involved in heart development. .
Tissue Specificity Widely expressed. In the embryo, expressed in the ventricular trabeculae, endothelial cells of the conotruncal cushions of the outflow tract and in the endothelial cells lining the developing aortic valves. .
Sequence Similarities Contains 1 CUE domain.
Subcellular Localization Membrane ; Peripheral membrane protein . Cytoplasm, cytosol . Following IL1 stimulation, translocation occurs from the membrane to cytosol.

Background for TGF-beta-activated kinase 1/MAP3K7-binding protein 2

Mitogen-activated protein kinase kinase kinase 7-interacting protein 2, also known as TAB2, is an enzyme that in humans is encoded by the MAP3K7IP2 gene. The protein encoded by this gene is an activator of MAP3K7/TAK1, which is required for the IL-1 induced activation of nuclear factor kappaB and MAPK8/JNK. This protein forms a kinase complex with TRAF6, MAP3K7 and TAB1, thus serves as an adaptor linking MAP3K7 and TRAF6. TAB2 functionally links TAK1 to TRAF6. What's more, TAB2 can act as a sensor for inflammatory signals by serving as a molecular beacon for recruitment of MEKK1(MAP3K1), which in turn mediated dismissal of the NCOR/HDAC complex and permitted derepression of AR and estrogen receptor target genes.

Customer Q&As

Q: Do you offer BSA-free antibodies? Keyword: Bovine serum albumin, carrier protein, conjugation
A: Yes, please contact us at for more information about BSA-free antibodies and availability. The new BSA-free formula uses trehalose as a replacement to BSA. We have tested many alternative chemicals and found that trehalose protects the antibodies the best.
Q: Is your western blot protocol provided from the website applicable for all your antibodies? Keyword: applications, WB
A: The protocol is applicable for all our antibodies in WB, the NC Membrane(0.45μm or 0.22μm) and transfer time(70 mins or 50 mins) depends on the protein molecular weight, details can be found in included protocol.
Q: Can I conjugate markers to this antibody? Can I link custom conjugates to this antibody? Keyword: conjugation
A: The antibody is stored with BSA and cannot be conjugated with markers. Carrier free antibodies are available upon request. Please contact
Q: What should I use for negative control?
A: Please contact us for negative control suggestions. You can also check expression databases such as genecards, uniprot etc. Due to logistic reasons, we do not sell serum or lysates that we use internally for positive or negative control.
Q: Where can I find troubleshooting information? What should I do if I have unexpected bands, high background, no signal, weak signal
A: You can find Boster's troubleshoot guides under tech support tab. Please contact us for further assistance on troubleshooting your experiment.
Q: What is the immunogen sequence of this antibody? Is this antibody polyclonal or monoclonal?
A: You can find the immunogen sequence under "Immunogen" and clonality in the product name.
Q: What is the expected band size? Why is it different than the observed band size?
A: The expected band size is predicted on the size of the protein. The actual band size may be affected by a few other factors including but not limited to:
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands

3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.

4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
Q: What is the suggested dilution ratio for Western Blot (WB), Immunohistochemistry (IHC) and or ELISA standards? What is the optimal pH for the sample?
A: Check the datasheet for the product for details on dilution ratios for different experiments. You can find the datasheet button on the right side of the product page.
Q: What is the protocol you used for your Western blotting (WB) and Immunohistochemistry (IHC)?
A: Check our protocols under the tech support tab.
