Covalent modification of the oncogene product Mdm2 by the ubiquitin-related protein SUMO1 protects it from ubiquitination and enhances its E3 ligase activity towards p53 in vitro. Disappearance of ...

Ubiquitin-specific protease 7 (USP7) is involved in DNA repair and cell cycle progression and, due to its control over the ubiquitination of key proteins, may impact oncogenes like MDM2 and c-Myc, as ...
