Mre11: roles in DNA repair beyond
homologous recombination
Shan Zha, Cristian Boboila & Frederick W Alt
The Mre11 protein has well-documented functions in the repair of DNA double-strand breaks via homologous
recombination. Now, several new studies reveal that Mre11 also has a role in mammalian DNA double-strand
break repair by nonhomologous end joining.
Eukaryotic cells have two well-characterized
DNA double-strand break (DSB) repair
pathways. Homologous recombination
accurately repairs postreplicative DSBs using
an intact template from a sister chromatid. In
contrast,nonhomologous end joining (NHEJ)
ligates DSBs without homology or with short
