Activation of NFkappaB requires that IkappaB be phosphorylated on specific serine residues, which results in targeted degradation of IkappaB. IkappaB kinase alpha (IKKalpha), previously designated CHUK, interacts with IkappaB-alpha and specifically phosphorylates IkappaB-alpha on the sites that trigger its degradation Serines 32 and 36. IKKalpha appears to be critical for NFkappaB activation in response to proinflammatory cytokines. Phosphorylation of IkappaB by IKKalpha is stimulated by the NFkappaB inducing kinase (NIK), which itself is a central regulator for NFkappaB activation in response to TNF and IL-1. The functional IKK complex contains three subunits, IKKalpha, IKKbeta and IKKgamma , and each appear to make essential contributions to IkappaB phosphorylation.
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
