- Cyclin D family member
- Cyclin D1
- Rb family members
- pRb/p105: pRb/p105 associates with the E2F activators and prevents them from stimulating the transcriptional activity of the promoters
- pRb/p107
- pRb2/p130: pRb2/p130 forms a complex with E2F4 (also with E2F5), which binds to promoters of genes required for S-phase entry, recruits a number of chromatin remodeling factors, such as SWI/SNF and HDAC thereby repress transcription
