Transcription factor E2F4 (E2F4)

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.

E2F4 binds with high affinity to RBL1 and RBL2. In some instances can also bind RB1.
