Re-evaluating cell-cycle regulation by E2Fs

Cell. 2006 Dec 1;127(5):871-4. doi: 10.1016/j.cell.2006.11.019.

Abstract

Activation of E2F transcription factors is thought to drive the expression of genes essential for the transition of cells from G1 to S phase and for the initiation of DNA replication. However, this textbook view of E2Fs is increasingly under challenge. Here we discuss an alternative model for how E2Fs may work.
