Abstract
Mutation of the Saccharomyces cerevisiae RAD52 epistasis group gene, MRE11, blocks meiotic recombination, confers profound sensitivity to double-strand break damage, and has a hyperrecombinational phenotype in mitotic cells. We isolated a highly conserved human MRE11 homologue using a two-hybrid screen for DNA ligase I-interacting proteins. Human MRE11 shares approximately 50% identity with its yeast counterpart over the N-terminal half of the protein. MRE11 is expressed at the highest levels in proliferating tissues, but is also observed in other tissues. The MRE11 locus maps to human chromosome 11q21 in a region frequently associated with cancer-related chromosomal abnormalities. A MRE11-related locus was found on chromosome 7q11.2-q11.3.
