| Attribute | Value |
|---|---|
| Gene Symbol | E2F1 |
| Full Name | E2F Transcription Factor 1 |
| Chromosomal Location | 20q11.22 |
| NCBI Gene ID | 1870 |
| Ensembl ID | ENSG00000101412 |
| UniProt ID | Q01094 |
| Gene Family | E2F transcription factor family |
| Protein Class | Transcription factor, Cell cycle regulator |
The E2F1 gene encodes E2F Transcription Factor 1, a key regulator of cell cycle progression from G1 to S phase. E2F1 is a DNA-binding protein that activates transcription of genes required for DNA replication and cell cycle progression. Beyond its canonical role in proliferation, E2F1 also functions in apoptosis, DNA damage response, and neuronal differentiation. Dysregulated E2F1 activity is implicated in cancer, neurodegeneration, and aging.
| Domain | Function |
|---|---|
| Transactivation domain (N-terminus) | Transcriptional activation |
| Pocket protein binding | Rb interaction |
| DNA-binding domain (C-terminus) | E2F target binding |
| Dimerization domain | DP protein heterodimerization |
E2F1 is a master regulator of G1/S transition:
| Category | Genes |
|---|---|
| DNA replication | DNA polymerase, PCNA, MCM proteins |
| Cell cycle | Cyclin E, CDK2, CDC25A |
| Apoptosis | P53, BAX, Apaf-1 |
| Metabolism | DHFR, TK, G6PD |
The study of E2F1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
