E2F's are DNA binding proteins, which associate with negative regulators, such as the retinoblastoma p107 protein, resulting in an altered rate of gene transcription. The E2F proteins contain several evolutionally conserved domains found in most members of the family. These domains include a DNA binding domain, a dimerization domain which determines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F2 and E2F3, have an additional cyclin binding domain. E2F1 is proposed to be involved in several cellular processes that range from tumor suppressor, cell progression and oncogenesis. E2F1 overexpression can also drive cells into apoptosis. Function: Transcription activator that binds DNA cooperatively with dp proteins through the E2 recognition site, 5'-TTTC[CG]CGC-3' found in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. E2F-1 binds preferentially RB1 protein, in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent apoptosis. Subunit: Component of the DRTF1/E2F transcription factor complex. Forms heterodimers with DP family members. The E2F-1 complex binds specifically hypophosphorylated retinoblastoma protein RB1. During the cell cycle, RB1 becomes phosphorylated in mid-to-late G1 phase, detaches from the DRTF1/E2F complex, rendering E2F transcriptionally active. Interacts with TRRAP, which probably mediates its interaction with histone acetyltransferase complexes, leading to transcription activation. Binds TOPBP1. Interacts with ARID3A (By similarity). Binds EAPP. Subcellular Location: Nucleus. Post-translational modifications: Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase (By similarity). Similarity: Belongs to the E2F/DP family. SWISS: Q01094 Gene ID: 1869 Database links: Entrez Gene: 1869 Human Omim: 189971 Human SwissProt: Q01094 Human Unigene: 654393 Human E2F1—屬于調(diào)節(jié)性轉(zhuǎn)錄因子E2F家族。有學(xué)者認為：E2F-1既可作為癌基因起作用，又可作為抑癌基因起作用。其不同可能由細胞中其他生長促進或抑制性蛋白質(zhì)水平和（或）活性決定，同時與細胞所處環(huán)境及器官特異性有關(guān)。在控制細胞周期和腫瘤抑制基因蛋白的活性方面起關(guān)鍵作用。 |
