 628-731 8.81e-58

cyclin box found in retinoblastoma-like protein (RBL) subfamily; The RBL subfamily includes two retinoblastoma-like proteins, RBL1 and RBL2. They are key regulators of entry into cell division and are directly involved in heterochromatin formation by maintaining overall chromatin structure. RBL1 and RBL2 recruit and target histone methyltransferases KMT5B and KMT5C, leading to epigenetic transcriptional repression. They control histone H4 'Lys-20' trimethylation and probably act as transcription repressors by recruiting chromatin-modifying enzymes to promoters. They may also act as tumor suppressors. Members of this family contain one cyclin box. The cyclin box is a protein binding domain.

 629-719 1.08e-34

cyclin box found in retinoblastoma-associated protein (RB) family; The RB family includes retinoblastoma-associated protein (RB), and two retinoblastoma-like proteins, RBL1 and RBL2. 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. It recruits and targets histone methyltransferases SUV39H1, KMT5B and KMT5C, leading to epigenetic transcriptional repression. RBL1 and RBL2 are also key regulators of entry into cell division. RBL1 and RBL2 recruit and target histone methyltransferases KMT5B and KMT5C, leading to epigenetic transcriptional repression. They control histone H4 'Lys-20' trimethylation and probably act as transcription repressors by recruiting chromatin-modifying enzymes to promoters. They may also act as tumor suppressors. Members of this family contain one cyclin box. The cyclin box is a protein binding domain.

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.

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.

 640-714 1.21e-03

Cyclin box fold superfamily; The cyclin box is a protein binding domain that functions in cell-cycle and transcriptional control. It is about 100 amino acids in length, composed of five helices, and is present in cyclins, transcription initiation factor IIB (TFIIB), and retinoblastoma tumour suppressor protein (Rb). Cyclins consist of 8 classes of cell cycle regulators that function as regulatory subunits of cyclin-dependent kinases (CDKs), which are serine/threonine kinases. The catalytic activities of CDKs are modulated not only by their interactions with cyclins but also by CDK inhibitors (CKIs). CDKs, cyclins and CKIs play key roles in transcription, epigenetic regulation, metabolism, stem cell self-renewal, neuronal functions, and spermatogenesis. TFIIB is a transcription factor that binds the TATA box. Members in this superfamily contain one or two copies of the cyclin box.
