DNA double strand breaks are the most cytotoxic lesions that can occur on the DNA. They can be repaired by different mechanisms and optimal survival requires a tight control between them. Here we uncover protein deneddylation as a major controller of repair pathway choice. Neddylation inhibition changes the normal repair profile toward an increase on(More)
The DNA damage response is vigorously activated by DNA double-strand breaks (DSBs). The chief mobilizer of the DSB response is the ATM protein kinase. We discovered that the COP9 signalosome (CSN) is a crucial player in the DSB response and an ATM target. CSN is a protein complex that regulates the activity of cullin ring ubiquitin ligase (CRL) complexes by(More)
The contribution of BRCA1 (breast cancer 1) to the repair of broken DNA is well established, but its real role at the molecular level is less well understood. By developing a new high-resolution, single-molecule technique, we have now shown that BRCA1 accelerates the processing of DNA breaks that subsequently engage in homologous recombination.
