E2F1 Antibody – Rabbit Polyclonal

E2F1: a member of the E2F/DP family of transcription factors.The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. Binds DNA cooperatively with Dp transcription factors in the promoter region of a number of genes whose products are involved in cell cycle regulation or in DNA replication.The Dp-1/E2F complex functions in the control of cell-cycle progression from G1 to S phase. 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. Phosphorylated by CDK2 and cyclin A-CDK2 in the S-phase. It can mediate both cell proliferation and p53-dependent apoptosis.
