StIKKing together: do multiple IKK pathways cooperate in the DNA-damage response?

ABSTRACT

Although IKK-related kinases are known to augment immune pathways, their importance to DNA-damage response has not been previously elucidated; in this issue of Molecular Cell, Renner et al. (2010) show that genotoxic stress requires SUMOylated IKKvarepsilon to regulate NF-kappaB transcription and cell survival.
