IKKα and IKKβ Regulation of DNA Damage-Induced Cleavage of Huntingtin

Abstract

These results indicate that DNA damage triggers cleavage of Htt and identify IKKbeta as a prominent regulator. Moreover, IKKbeta-dependent reduction of Bcl-xL is important in this process. Thus, inhibition of IKKbeta may promote neuronal survival in HD as well as other DNA damage-induced neurodegenerative disorders.
