Summary
MAP3K7IP2 (TAB2) interacts with both MAP3K7 (TAK1) and TRAF6 and promotes their association, thereby triggering subsequent interleukin-1 signalling events.
MAP3K7IP2 (TAB2) and MAP3K7IP2 (TAB3) activate the NF-kappaB pathway through binding to K63-linked polyubiquitin chains.
MAP3K7IP2 binds to K-63 polyubiquitinated TRAF2 and this association is required for activation of downstream IKK and JNK kinases.
MAP3K7IP2 (TAB2) activates MAP3K7 (TAK1) and also plays an essential role in the deactivation of TAK1 by recruiting PP6 through a polyubiquitin chain-dependent mechanism.
MAP3K7IP2 is an adapter linking MAP3K7 (TAK1) and TRAF6 and also functions as a mediator of TAK1 activation in the IL-1 signalling pathway.
MAP3K7IP2 (TAB2) and MAP3K7IP3 (TAB3) function redundantly as mediators of TAK1 activation in IL-1 and TNF signal transduction.
Entrez Gene
Summary The protein encoded by this gene is an activator of MAP3K7/TAK1, which is required for 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. This protein, TAB1, and MAP3K7 also participate in the signal transduction induced by TNFSF11/RANKl through the activation of the receptor activator of NF-kappB (TNFRSF11A/RANK), which may regulate the development and function of osteoclasts.
