IKK alpha Rabbit Polyclonal Antibody

Inhibitor of nuclear factor kappa-B kinase subunit alpha (IKK-α) also known as IKK1 or conserved helix-loop-helix ubiquitous kinase (CHUK) is a protein kinase that in humans is encoded by the CHUK gene. IKK-α is part of the IκB kinase complex that plays an important role in regulating the NF-κB transcription factor. However, IKK-α has many additional cellular targets, and is thought to function independently of the NF-κB pathway to regulate epidermal differentiation. 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. Mutations in IKK-α in humans have been linked to lethal fetal malformations. The phenotype of these mutant fetuses is similar to the mouse IKK-α null phenotype, and is characterized by shiny, thickened skin and truncated limbs. Decreased IKK-α activity has been reported in a large percentage of human squamous cell carcinomas, and restoring IKK-α in mouse models of skin cancer has been shown to have an anti-tumorigenic effect.
