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 … WebDec 8, 2024 · AT5G22220.3. E2F transcription factor 1. E2F/DP Family Introduction. E2F transcription factors are a family of proteins that share a related DNA-binding domain and that bind to overlapping sets of target promoters. Most E2F proteins associate with a DP protein and form heterodimeric complexes that bind to DNA in a sequence-specific manner.
WebE2F transcription factors control the expression of genes involved in a variety of essential cellular processes and consequently their activity needs to be tightly regulated. Protein-protein interactions are thought to be key modulators of E2F activity.
