Cyclin A1 contributes to G1 to S cell cycle progression in somatic cells. Cyclin A1 overexpression enhances S phase entry consistent with an oncogenic function. Finally, cyclin A1 might be a therapeutic target since its silencing inhibited leukemia cell growth. |

Among them, CDK3 is critically important because it triggers the transitions of G0 to G1 and G1 to S phase through binding to cyclin C and cyclin E1, respectively. |

In its hypophosphorylated state, pRb binds transcription factors of the E2F family which are required for cell cycle progression. As the level of CyclinD/Cdk4/6 complexes increases, pRb becomes phosphorylated and progression through G1 occurs. At a critical level of phosphorylation, E2F is released from pRb. This activates the transcription of CyclinE which complexes with Cdk2 to fully release pRb repression by further phosphorylation, establishing a positive feedback loop. E2F further promotes the transcription of S-phase genes. Thus, CyclinD/Cdk4/6 and CyclinE/Cdk2 together regulate S-phase entry via phosphorylating pRb, which controls pRb binding to E2F |

In addition to the successive phosphorylation of pRb by active Cyclin/Cdk complexes, other factors can also impact upon S-phase entry Subsequently, the initiation of replication requires the formation of a pre-initiation complex (pre-IC) that is initiated by phosphorylation of Mcm2-7 by CyclinE/Cdk2 and DDK (Dbf4- and Drf1-dependent kinase) and recruitment of Cdc45 onto the chromatin (Figure 1). This recruitment is thought to be the critical step for the activation of the Mcm2-7 helicase activity and replication initiation. Finally, unwinding of the chromatin enables DNA-polymerase _ to initiate DNA synthesis and DNA-polymerase _ to continue replication |

This result would suggest that Rif1 acts in an intra-S-phase checkpoint pathway that is separate from the Nbs1 pathway. Although a role for human Rif1 at telomeres is not excluded, our data show that the primary function of Rif1 is in the DNA-damage response. Rif1 localizes to DSBs in an ATM- and 53BP1-dependent manner and functions in the intra-S-phase checkpoint that serves to slow down DNA synthesis when DNA damage has occurred. |
