DNA Repair: Structure Of The Mre11 Protein Bound To DNA

Monday, October 27, 2008 - 15:14 in Biology & Nature

DNA repair is critical for avoiding cancer and other diseases. A molecular machine called the MRN complex finds and signals double-strand breaks and initiates error-free repair by means of homologous recombination. Researchers have solved the structure of MRN's core protein, called Mre11, and learned how it does its job.
