Dual contributions of Xrp1 to genome integrity through the DNA damage response and cell competition

Model organisms may help understand how p53 suppresses tumorigenesis in mammals. In Drosophila, the primary transcriptional target of p53 is the gene encoding the bZip AT-hook protein Xrp1, which is another transcription factor. We report that Xrp1 mediates multiple functions of p53 in the DNA damage response (DDR), co...
