High impact information on MRE11A

  • In contrast, concomitant interference with Nbs1-Mre11 and the Chk2-Cdc25A-Cdk2 pathways entirely abolishes inhibition of DNA synthesis induced by ionizing radiation, resulting in complete RDS analogous to that caused by defective ATM [7].
  • The Mre11 complex is required for repair of hairpin-capped double-strand breaks and prevention of chromosome rearrangements [8].
  • Our results suggest an additional role for the Mre11 complex in maintaining genome stability [8].
  • The NBSp26 protein is not physically associated with the MRE11 complex, whereas the p70 species is physically associated with it [9].
  • To clarify functions of the Mre11/Rad50 (MR) complex in DNA double-strand break repair, we report Pyrococcus furiosus Mre11 crystal structures, revealing a protein phosphatase-like, dimanganese binding domain capped by a unique domain controlling active site access [10].

Associations of MRE11A with chemical compounds

 

Physical interactions of MRE11A

  • The Mre11 complex is required for ATM activation and the G2/M checkpoint [25].
  • Linkage between Werner syndrome protein and the Mre11 complex via Nbs1 [26].
  • Consequently, the FHA/BRCT domain is likely to have a crucial role for both binding to histone and for relocalization of hMRE11/hRAD50 nuclease complex to the vicinity of DNA damage [27].
  • Nbs1 is required for the Mre11 complex promotion of WRN helicase activity [26].
  • Here, we discuss how WRN, the MRE11 complex and the ATR kinase could work together in response to replication blockage to avoid DNA replication fork collapse and genome instability [28].
 

Enzymatic interactions of MRE11A

 

Co-localisations of MRE11A

  • In response to gamma-irradiation or mitomycin C, WRN leaves the nucleoli and co-localizes with the Mre11 complex in the nucleoplasm [26].
 

Regulatory relationships of MRE11A

  • Downregulation of MDC1 expression by small interfering RNA yields a radio-resistant DNA synthesis (RDS) phenotype and prevents ionizing radiation-induced focus formation by the MRE11 complex [30].
  • NBS cells are also deficient for radiation-induced nuclear foci containing Mre11, while those with Rad51 are unaffected [31].
  • New data suggest that the Mre11 complex can directly activate the ATM checkpoint kinase at DNA breaks [32].
  • Alternatively, the elevated yield of Mre11 foci positive cells following wortmannin treatment may reflect an overall perturbation to the signaling cascades regulated by wortmannin-sensitive PI3 related kinases [33].
  • ATM and ATR promote Mre11 dependent restart of collapsed replication forks and prevent accumulation of DNA breaks [34].
