 IKK-α is sulfenylated at a conserved cysteine residue in the kinase domain, which correlated with derepression of EGF promoter activity and increased EGF expression, indicating that IKK-α stimulatea migration through dynamic interactions with the EGF promoter depending on the redox state within cells.IKK-α has also been reported to regulate the cell cycle protein cyclin D1 in an NF-κB-independent manner.Inhibition of IκB kinase (IKK) and IKK-related kinases, IKBKE (IKKε) and TANK-binding kinase 1 (TBK1), has been investigated as a therapeutic option for the treatment of inflammatory diseases and cancer.
