Background

Mre11, originally described in genetic screens from the yeast Saccharomyces cerevisiae in which mutants were defective in meiotic recombination, is a central part of a multisubunit nuclease composed of Mre11, Rad50 and Nbs1. The MRN complex plays a critical role in sensing, processing and repairing DNA double strand breaks. Defects lead to genomic instability, telomere shortening, aberrant meiosis and hypersensitivity to DNA damage. Hypomorphic mutations of Mre11 are found in ataxia-telangiectasia-like disease, with phenotypes similar to mutations in ATM that cause ataxia-telangiectasia, including a predisposition to malignancy in humans. Cellular consequences of ATLD include chromosomal instability and defects in the intra-S phase and G2/M checkpoints in response to DNA damage. The MRN complex may directly activate the ATM checkpoint kinase at DNA breaks.
