The retinoblastoma tumour suppressor protein (R regulates a number of diverse cellular functions including differentiation, angiogenesis, chromatin remodelling, senescence and apoptosis. The best-characterised function of RB is cell cycle regulation, and it has been considered a phosphoprotein regulated by cyclin-dependent kinases. In its hypophosphorylated form, RB binds the transcription factor E2F1, arresting the cell cycle in the G1 phase. Here, we show that MDM2 controls the cell cycle through synthesis and degradation of RB pro
