| Post Translational Modifications | Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. Phosphorylation at Ser-364 by CHEK2 stabilizes E2F1 upon DNA damage and regulates its effect on transcription and apoptosis. Phosphorylation at Ser-403 by GSK3B promotes interaction with USP11, leading to its deubiquitination and stabilization. Ubiquitinated via 'Lys-63'-linked ubiquitin, leading to its degradation. Deubiquitinated by USP11 following phosphorylation by GSK3B, promoting its stability. Acetylation stimulates DNA-binding. Enhanced under stress conditions such as DNA damage and inhibited by retinoblastoma protein RB1. Regulated by KAP1/TRIM28 which recruits HDAC1 to E2F1 resulting in deacetylation. Acetylated by P/CAF/KAT2B. Methylation at Lys-185 by SETD7 promotes E2F1 ubiquitin-dependent proteasomal degradation. |
| Function | Transcription activator that binds DNA cooperatively with DP proteins through the E2 recognition site, 5'-TTTCCGCGC-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. E2F1 binds preferentially RB1 in a cell-cycle dependent manner. It can mediate both cell proliferation and TP53/p53-dependent apoptosis. Blocks adipocyte differentiation by binding to specific promoters repressing CEBPA binding to its target gene promoters. Directly activates transcription of PEG10. Positively regulates transcription of RRP1B. |
