PF16421E2F transcription factor CC-MB domain (E2F_CC-MB)E2F transcription factor CC-MB domainThis 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

This domain has a strand-loop-helix structure, which directly interacts with both E2F1 and DP1, followed by a tail segment that lacks regular secondary structure [1].
