General description

Transcription factor E2F1 (UniProt: Q01094; also known as E2F-1, PBR3, Retinoblastoma-associated protein 1, RBAP-1, Retinoblastoma-binding protein 3, RBBP-3, pRB-binding protein E2F-1) is encoded by the E2F1 (also known as RBBP3) gene (Gene ID: 1869) in human. E2F-1 is a 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. It is a component of the DRTF1/E2F transcription factor complex and forms heterodimers with DP family members. The DRTF1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. The E2F1 complex is shown to bind specifically hypophosphorylated retinoblastoma protein RB1. During the cell cycle, RB1 becomes phosphorylated in mid-to-late G1 phase and detaches from the DRTF1/E2F complex that renders E2F transcriptionally active. E2F-1 can be phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. It is also phosphorylated at serine 364 by CHEK2, which stabilizes it upon DNA damage and regulates its effect on transcription and apoptosis. Acetylation of E2F-1 by P/CAF/KAT2B stimulates its DNA-binding.
