"Different from the interaction of USP28 with LSD1, USP28 mediated p53BP1 stabilization only occurs after DNA damage and no effect is found in the absence of DNA damage, suggesting that the interaction between USP28 with p53BP1 is regulated by DNA damaging."

"However, USP28 loss did not strongly impair DDR signaling or DNA repair, consistent with previous work that found the 53BP1-BRCT domains were not required for the DNA repair functions of 53BP1(Figure 1A) (Knobel et al., 2014; Ward et al., 2006)."
