Research Abstract

To ensure that DNA replication is limited to only once during a cell cycle, initiator protein Cdt1 is degraded once DNA replication is initiated. We examined how PCNA dependent CRL4-Cdt2 operates for the degradation of Cdt1.We report that CRL4-Cdt2 recognizes specific residues located at the N-terminus of Cdt1 and that PCNA loaders are differentially required during S phase and repair. Cdt1 degradation is strictly regulated to maintain genome integrity.
