E2f transcription factor plant
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 … WebApr 18, 2005 · The E2 factor (E2F) family of transcription factors are downstream targets of the retinoblastoma protein. ... 2000) and in several different plant species (Ramirez …

WebTranscriptional Regulation by the E2F Transcription Factors. E2F was originally identified as a cellular DNA binding activity that regulated expression of the viral E2 promoter.30,31 Since this seminal work, molecular analysis has revealed that the E2F activity is encoded by a family of DNA binding proteins, which includes transcriptional ...
WebAs major regulators of the cell cycle, apoptosis and differentiation, E2F transcription factors have been studied extensively in a broad range of organisms. The recent identification of atypical E2F family members further expands our structural, functional and molecular view of the cellular E2F activity. Unlike other family members, atypical E2Fs … WebThe primary C. elegans E2F transcription factor, EFL-1 (E2F like-1), is most similar to mammalian E2F4 and E2F5 (Refs 45, 46). EFL-1 probably functions as a heterodimer with DPL-1 , which is ...
WebThe E2F transcription factors are key components of the cyclin D/retinoblastoma/E2F pathway. Here we demonstrate thatArabidopsis thaliana contains six functional AtE2F genes that are all expressed in cell suspension culture but show different patterns of expression during cell cycle progression. According to their structural and functional features, the six … WebTo elucidate the epigenetic maintenance mechanism for functional plant centromeres, we studied transcriptional regulation of the centromere-specific histone H3 variant CENH3 in Arabidopsis thaliana. We focused on the structure and activity of the CENH3 promoter (CENH3pro) and its regulation by E2F transcription factors.Use of CENH3pro::GUS …
