LT inhibits localization of repair proteins into nuclear foci after UV exposure. A

<p>: Uninduced MEFs or MEFs expressing either LT or K308E were exposed to 40 J/m² UV. After one hour, they were stained with antibody to RPA70 (FITC), RAD51 (TRITC). Individual fluorescence images and the merged DAPI images that stain nuclei are shown. <b>B</b>: Uninduced MEFs or MEFs expressing either LT or K308E were exposed to 40 J/m² UV.
