WebNov 1, 2002 · The E2F–Rb pathway controls the G1-to-S-phase transition by the timely activation of genes involved in DNA synthesis and cell-cycle control. Recent findings reveal that the E2F–Rb pathway communicates with chromatin-remodelling factors in the control of transcription and cell-cycle progression. WebRb appears to repress transcription of these genes through its interaction with E2F (Blake and Azizkhan 1989; Thalmeier et al. 1989; Dalton 1992; Ohtani et al. 1995). Recent findings in the Rb/E2F field are clarifying how this pathway regulates the transition from G 1 to S phase at the molecular level. Other emerging results
