TAB3 (TAK1-Binding Protein 3) is a paralog of TAB2 that also functions as a TAK1 adaptor protein. TAB3 contains similar domain architecture to TAB2: a coiled-coil domain, zinc finger, and TAK1-binding domain. TAB3 can compensate for TAB2 in some contexts and may have tissue-specific functions. TAB3 is involved in NF-κB and MAPK activation downstream of cytokine receptors and TLRs. In the brain, TAB3 expression in microglia and neurons contributes to inflammatory signaling. TAB3-mediated TAK1 activation has been implicated in neuroinflammation and neuronal death. The TAB3-TAK1 axis represents a potential target for anti-inflammatory therapies in neurodegenerative diseases.
TAB3 Protein is a TAK1-binding proteins. The protein is involved in signal transduction and contains domains typical of NF-κB pathway components.
TAB3 is a homolog of TAB2 that also links TAK1 to TRAF6 in NF-κB signaling. It contains a zinc finger domain that binds polyubiquitin chains. TAB3 may have partially redundant functions with TAB2 and is involved in stress responses and inflammation.
TAB3 is implicated in inflammatory and autoimmune diseases.
