Conserved helix-loop-helix ubiquitous kinase, abbreviated for CHUK, is also called inhibitor of nuclear factor kappa-B kinase subunit alpha (IKK-α/IKKA) or IKK1 [1]. IKK-α, a serine⁄threonine kinase, belongs to the catalytic component of the inhibitor of the NF-kappa B Kinase(IKK) complex that plays a central role in regulating the NF-κB transcription factor [2]. Under homeostatic conditions, NF-κ B is weakly active due to cytoplasmic sequestration via noncovalent binding to IκB (inhibitor of NF-κB) proteins [3]. An NF-κB-inducing kinase (NIK), a central signaling component of the noncanonical NF-κB pathway, is targeted for continuous degradation by a tumor necrosis factor (TNF) receptor-associated factor-3 (TRAF3)-dependent E3 ubiquitin ligase [4]. Stimulated by non-canonical signals, NIK is stabilized from proteolysis to the extent that it becomes capable of recruiting and inducing the kinase activity of IKK-α [5] Subsequently, IKK-α and NIK phosphorylate three serines of NF-κB2/β100 within its C-terminal IκBδ segment, leading to the processing of NF-κB2 precursor protein p100 to p52. Phosphorylation-dependent ubiquitylation and proteasomal degradation of the IκB proteins lead to the release of active NF-κB dimers [6]. In turn, free NF-κB is translocated into the nucleus and activates the transcription of multiple genes involved in immune response, growth control, or protection against apoptosis. Since weak IKK- α activity has been reported in a large percentage of human squamous cell carcinomas, Lahtela J et al. found that normalizing IKK-α in mouse models of skin cancer exhibited an anti-tumorigenic effect [7]. IKK-α mutations in humans have been associated with lethal fetal malformations, which are characterized by shiny, thickened skin and truncated limbs in appearance [8].
