Rb C-terminal domain; The Rb C-terminal domain is required for high-affinity binding to E2F-DP complexes and for maximal repression of E2F-responsive promoters, thereby acting as a growth suppressor by blocking the G1-S transition of the cell cycle. 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.

 645-771 1.00e-75

cyclin box found in retinoblastoma-associated protein (RB) and similar proteins; RB, also called p105-Rb, pRb, or pp110, is a key regulator of entry into cell division and also acts as a tumor suppressor. It promotes G0-G1 transition when phosphorylated by CDK3/cyclin-C. It also acts as a transcription repressor of E2F1 target genes. RB is directly involved in heterochromatin formation by maintaining overall chromatin structure, especially that of constitutive heterochromatin by stabilizing histone methylation. It recruits and targets histone methyltransferases SUV39H1, KMT5B and KMT5C, leading to epigenetic transcriptional repression. It controls histone H4 'Lys-20' trimethylation. RB contains one cyclin box. The cyclin box is a protein binding domain.

 645-771 1.00e-75

cyclin box found in retinoblastoma-associated protein (RB) and similar proteins; RB, also called p105-Rb, pRb, or pp110, is a key regulator of entry into cell division and also acts as a tumor suppressor. It promotes G0-G1 transition when phosphorylated by CDK3/cyclin-C. It also acts as a transcription repressor of E2F1 target genes. RB is directly involved in heterochromatin formation by maintaining overall chromatin structure, especially that of constitutive heterochromatin by stabilizing histone methylation. It recruits and targets histone methyltransferases SUV39H1, KMT5B and KMT5C, leading to epigenetic transcriptional repression. It controls histone H4 'Lys-20' trimethylation. RB contains one cyclin box. The cyclin box is a protein binding domain.

Retinoblastoma-associated protein B domain; The crystal structure of the Rb pocket bound to a nine-residue E7 peptide containing the LxCxE motif, shared by other Rb-binding viral and cellular proteins, shows that the LxCxE peptide binds a highly conserved groove on the B domain. The B domain has a cyclin fold.

cyclin box found in Arabidopsis thaliana retinoblastoma-related protein 1 (AtRBR1) and similar proteins; AtRBR1 is a key regulator of entry into cell division. It acts as a transcription repressor of E2F target genes, whose activity is required for progress from the G1 to the S phase of the cell cycle. AtRBR1 plays a central role in the mechanism controlling meristem cell differentiation, cell fate establishment and cell fate maintenance during organogenesis and gametogenesis. AtRBR1 contains one cyclin box. The cyclin box is a protein binding domain.
