Description_x000D_ General description_x000D_ IKKgamma 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. IKKgamma forms dimers and trimers and interacts preferentially with IKKbeta but not IKKalpha. IKKgamma associates with activated ATM after the induction of DNA double-strand breaks. ATM phosphorylates serine-85 of IKKgamma to promote its ubiquitin-dependent nuclear export._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 10 mM glutathione, 0.1 mM EDTA, 0.25 mM DTT, 0.1 mM PMSF, 25% glycerol._x000D_ Preparation Note_x000D_ After opening, aliquot into smaller quantities and store at -70 °C.
