General description

IKKbeta is a serine/threonine protein kinase that phosphorylates the I-kappa-B protein which is an inhibitor of the transcription factor NF-kappa-B complex. Phosphorylation of I-kappa-B protein triggers the degradation of the inhibitor via the ubiquitination pathway, thereby activating NF-kappa-B complex. The activity of IKKbeta is stimulated by TNF and IL1 and IKKbeta forms a heterodimer that interacts with NIK. Overexpression of catalytically inactive IKKbeta blocks cytokine-induced NF-kappa-B activation. Aspirin and sodium salicylate can specifically inhibit IKKbeta activity in vitro and in vivo by binding to IKKbeta to reduce ATP binding.
