"Here, we report that in response to DNA damage USP7 is downregulated by the ATM dependent protein phosphatase PPM1G, thus downregulating Mdm2 and activating the p53 response.|We have now shown that when DNA damage is detected, PPM1G is activated and dephosphorylates USP7 isoform protein that leads to its degradation and consequently to Mdm2 degradation and accumulation of p53 ( A)."
