WebE2F is a group of genes that encodes a family of transcription factors (TF) in higher eukaryotes.Three of them are activators: E2F1, 2 and E2F3a. Six others act as suppressors: E2F3b, E2F4-8. All of them are involved in the cell cycle regulation and synthesis of DNA in mammalian cells. E2Fs as TFs bind to the TTTCCCGC (or slight variations of this … WebThe transcription factor E2F, the principal target of the tumor suppressor pRB, plays crucial roles in cell proliferation and tumor suppression. In almost all cancers, pRB function is disabled, and E2F activity is enhanced. To specifically target cancer cells, trials have been undertaken to suppress enhanced E2F activity to restrain cell proliferation or selectively …

WebMay 1, 2013 · Importantly, additional observations argue that pRB plays a direct and broadly applicable role in this pathway. First, a fraction of endogenous pRB, including some cdk-phosphorylated pRB, is constitutively localized on the outside of mitochondria. Second, recombinant pRB is able to induce MOMP and liposome permeabilization in vitro. WebIn addition, DNA endoreduplication occurred in pRb-negative but not in pRb-positive cells, suggesting that functional pRb is necessary to prevent DNA replication in p21 G 2-arrested cells.
