|Description||The nuclear transcription factor kappa-B, NF-kappaB, is controlled by interaction with an inhibitory subunit, I-kappaB, which restricts NF-kappaB to the cytoplasm. Following stimulation by various cytokines or other stimuli, I-kappaB becomes degraded and NF-kappaB is released to the nucleus. The release of I-kappaB from NF-kappaB is thought to be a critical point in the activation of NF-kappaB signal pathways. A group of proteins form an NF-kappaB regulatory complex, or signalsome. Two members of this complex are a pair of closely related kinases, IKKalpha and IKKbeta (also called IKK-1 and IKK-2). IKKalpha and IKKbeta are serine/threonine kinases which share approximately 50% sequence identity. In addition to their kinase domains, these proteins each contain leucine zipper and helix-loop-helix regions which facilitate their interaction with each other as well as interaction(s) with other proteins within the IKK complex. Both IKKalpha and IKKbeta phosphorylate critical residues of I-kappaB, thus targeting it for subsequent degradation. IKKalpha and IKKbeta become activated themselves following phosphorylation by upstream kinases, including NF-kappaB-inducing kinase (NIK) and MEKK1. Thus the IKK kinases play an important role in the activation of NF-kappaB. IKKalpha migrates at a molecular weight of 85 kD in SDS-PAGE. Clone B78-1 recognizes human IKKalpha. It does not cross-react with IKKbeta. Full length, recombinant human IKKalpha was used as immunogen. The reactivity of B78-1 was verified by immunoprecipitation and western blot analysis.|
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
