MDM2, a ubiquitin ligase for p53, plays a central role in regulation of the stability of p53 . Akt-mediated phosphorylation of MDM2 at Ser166 and Ser186 increases its interaction with p300, allowing MDM2-mediated ubiquitination and degradation of p53 . Phosphorylation of MDM2 also blocks its binding to p19ARF, increasing the degradation of p53 .1) Haupt, Y. et al. (1997) Nature 387, 296-299. Mayo, L. D. and Donner, D. B. (2001) Proc. Natl. Acad.
