In the original version of [Fig. S2](#sfig2){ref-type="fig"}, the panel showing staining with anti-RAD51 in non-irradiated (0 Gy) *Brca2* ^*WT/WT*^ cells was incorrect. A corrected version of [Fig. S2](#sfig2){ref-type="fig"} is shown below.

![**RAD51 foci induction in** ***Brca2*^*GFP/GFP*^** **cells**. Confocal microphotographs of wild-type and *Brca2* ^*GFP/GFP*^ cells were stained by indirect immunofluorescence with anti-RAD51 antibody (red). BRCA2-GFP is visualized directly (green); the nuclei of wild-type cells imaged under the same settings emit low levels of background fluorescence. Nuclear DNA is stained with DAPI (blue). The number of RAD51 foci per confocal slice of a nucleus was determined in 30--35 randomly sampled nuclei per each condition. An arbitrary cutoff of 10 foci per nucleus was used to define positive cells. Bars, 10 µm.](JCB_20140501402182015c_Fig1){#sfig2}
