PF08781 | Transcription factor DP (DP) | Transcription factor DP | DP forms a heterodimer with E2F and regulates genes involved in cell cycle progression. The transcriptional activity of E2F is inhibited by the retinoblastoma protein which binds to the E2F-DP heterodimer [2] and negatively regulates the G1-S transi ... | Domain | |
PF16421 | E2F transcription factor CC-MB domain (E2F_CC-MB) | E2F transcription factor CC-MB domain | This is the coiled coil (CC) - marked box (MB) domain of E2F transcription factors. This domain forms a heterodimer with the corresponding domain of the DP transcription factor, the heterodimer binds the C-terminus of retinoblastoma protein [1]. | Domain | |
