TAB3 Antibody

TAB3, a TAB2-like protein, is a mediator of TAK1 activation in IL-1 and TNF signaling. IL-1 and TNF are cytokines involved in the inflammation process, initiating signaling cascades leading to the activation of NF-kB and mitogen-activated protein kinases (MAPKs). TAB3 functions as an adapter, linking TAK1 and TRAF6 or TRAF2. This kinase complex phosphorylates IkB, which keeps NF-kB inactive and sequestered in the cytoplasm. Phosphorylation leads to IkB degradation, activating NF-kB, which translocates to the nucleus, binds to DNA response elements and can begin multiple signaling cascades.
