Upon DNA damage, eukaryotic cells initiate the DNA damage response, a complex signalling pathway which coordinates cell cycle arrest with DNA repair. Using a genome-wide RNA interference screen, the human F-box protein FBXO31 is shown to regulate the G1/S cell cycle transition in response to DNA damage by mediating degradation of cyclin D1, an important regulator of progression from G1 to S phase.
