The protein ataxia-telangiectasia mutated (ATM) detects DNA damage and can trigger cellular apoptosis, but how this process is regulated at the molecular level is unclear. Here, Chunget al. show that the transcription factor FOXO3 controls the formation of ATM-containing signalling complexes at sites of DNA damage that trigger apoptosis.
