"For example , USP7 regulates the stability of both p53 and Mdm2 and maintains p53 ubiquitination levels ; 120 USP2 mediates the stability of Mdm2 ; 121 USP10 modulates p53 localization and stability ; 122 OTUB1 abrogates p53 ubiquitination and activates p53.123 Interestingly , USP10 can stabilize both mutated and wild-type p53 , with a dual role in tumorigenesis ."
