The IKKbeta and NEMO/IKKgamma subunits of the NF-kappaB-activating signalsome complex are known to be essential for activating NF-kappaB by inflammatory and other stress-like stimuli. However, the IKKalpha subunit is believed to be dispensable for the latter responses and instead functions as an in vivo mediator of other novel NF-kappaB-dependent and(More)
NF-kappaB transcription factors induce a host of genes involved in pro-inflammatory/stress-like responses; but the collateral effects and consequences of sustained NF-kappaB activation on other cellular gene expression programming remain less well understood. Here enforced expression of a constitutively active IKKbeta T-loop mutant (IKKbetaca) drove murine(More)
Cellular responses to stress-like stimuli require the IkappaB kinase (IKK) signalsome (IKKalpha, IKKbeta, and NEMO/IKKgamma) to activate NF-kappaB-dependent genes. IKKbeta and NEMO/IKKgamma are required to release NF-kappaB p65/p50 heterodimers from IkappaBalpha, resulting in their nuclear migration and sequence-specific DNA binding; but IKKalpha was found(More)
