In the above article, the sentence “This study was the first to identify a protein (YB1) involved in mitochondrial MMR” incorrectly appeared below reference 107 instead of below reference 103 (de Souza-Pinto, N. C. et al. Novel DNA mismatch-repair activity involving YB-1 in human mitochondria. DNA Repair 8, 704–719 (2009)). This has been corrected online. The authors apologize for any confusion caused to readers.
