abstract：:The Mre11 complex (Mre11-Rad50-Nbs1) is involved in a diverse array of DNA metabolic processes including the response to DNA double-strand breaks (DSBs). The structure of Rad50 plays a key role in the DNA-binding and end-bridging activity of the complex. An interesting feature within the central portion of the Rad50 p...
