NF-κB (nuclear factor κB) is sequestered in the cytoplasm by IκB family of inhibitory proteins that mask the nuclear localization signal of NF-κB thereby preventing translocation of NF-κB to the nucleus. External stimuli such as tumor necrosis factor or other cytokines results in phosphorylation and degradation of IκB releasing NF-κB dimers. NF-κB dimer subsequently translocates to the nucleus and activates target genes. Synthesis of IκBα is autoregulated. IκB proteins are phosphorylated by IκB kinase complex consisting of at least three proteins, IKKα, IKKβ, and IKKγ. IKKα and IKKβ are phosphorylated by NF-κB-inducing kinase (NIK) and MAP kinase kinase kinase-1 (MEKK1), respectively. Recent studies have shown that IKKβ, not IKKα, is the target of proinflammatory stimuli. Targeted disruption of IKKβ gene in mice also results in extensive liver damage from apotopsis and death during embryo development.

Western blot analysis of IKKα in human Daudi cells. The blot was probed with mouse monoclonal IKKα (IM4761) at 1:500.

Immunohistochemical analysis of IKKα in formalin-fixed, paraffin-embedded human cervix tissue using an isotype control antibody (top left) and IKKα antibody (bottom left and right) at 1:100.

Clone 14A231 was generated from His-tagged full length IKKα. This sequence is well conserved in rat and mouse IKKα.
