Detection of DNA double-strand breaks (DSBs) involves sensor proteins of the MRN complex, composed of MRE11A, RAD50 and NBN (NBS1). Binding of the MRN complex to DNA DSBs activates ATM-dependent DNA damage signaling cascade, by promoting KAT5 (Tip60) mediated acetylation of ATM and subsequent ATM autophosphorylation. Activated ATM triggers and coordinates recruitment of repair proteins to DNA DSBs (Beamish et al. 2002, Thompson and Schild 2002, Bakkenist et al. 2003, Lee and Paull 2005, Sun et al. 2005, Sun et al. 2007, Ciccia and Elledge 2010).
