The ends in sight: Mre11-Rad50-Nbs1 complex structures come into focus

Mol Cell. 2023 Jan 19;83(2):160-162. doi: 10.1016/j.molcel.2022.12.016.

Abstract

In this issue of Molecular Cell, Rotheneder et al.1 elucidate the eukaroytic Mre11-Rad50-Nbs1 (MRN) complex quaternary architecture, which together with cryo-EM structures of bacterial Mre11-Rad50-DNA complexes,2 resolves the basis for MRN assembly and its broad nuclease specificity regulating DNA double-strand break repair.
