Abstract :
Cells exposed to genotoxic insults such as ionizing radiation activate a signaling cascade to repair the damaged DNA. Two recent articles published in Nature show that such genome maintenance requires modifications of tumor suppressor proteins BRCA1 and 53BP1 by the small ubiquitin-like modifier SUMO.
