Nahas, Midori Mitui, Kristin M. Gamo, Liutao Du, and Richard A. Gatti, which appeared in issue 44, November 2, 2004, of Proc. Natl. Acad. Sci. USA (101, 15676–15681; first published October 21, 2004; 10.1073/pnas.0405155101), due to a PNAS error, Fig. 5 did not appear in color. The corrected figure and its legend appear below.

Fig. 5.

ATM pS1981 IRIFs of AT187LA cells after treatment with geneticin. Cells were irradiated with 10 Gy and were incubated for 45 min at 37°C before fixation on coverslips. ATM pS1981 IRIFs were not observed in untreated cells; maximum intensity of staining was seen in the nuclei of cells exposed to 75 μg/ml. Nonirradiated cells, untreated or exposed to comparable concentrations of geneticin, showed only occasional foci.
