The DNA replication-licensing factor Cdt1 is present during the G1 phase of the cell cycle. When cells initiate S phase or are UV-irradiated, Cdt1 is recruited to chromatin-bound PCNA and ubiquitinated by CRL4(Cdt2) for degradation. In both situat...

Recent work identified the E3 ubiquitin ligase CRL4(Cdt2) as mediating the timely degradation of Cdt1 during DNA replication and following DNA damage. In both cases, proliferating cell nuclear antigen (PCNA) loaded on chromatin mediates the CRL4(C...
Background: Maintenance of genome integrity is crucial for the propagation of the genetic information. Cdt1 is a major component of the pre-replicative complex, which controls once per cell cycle DNA replication. Upon DNA damage, Cdt1 is rapidly t...

For genomic integrity to be maintained, the cell cycle and DNA damage responses must be linked. Cdt1, a G1-specific cell-cycle factor, is targeted for proteolysis by the Cul4-Ddb1(Cdt2) ubiquitin ligase following DNA damage. Using a laser nanosurg...
