Communication between Mre11 and Rad50 in the MR complex is critical for the sensing, damage signaling, and repair of DNA double-strand breaks. Mre11 protein consists of an N-terminal core domain and a C-terminal domain linked by an extended connecting loop. The C-terminal domain of Mre11 is composed of three helices and binds to the C-terminal part of the Rad50 coiled-coil [1].	Domain
