An Evolutionarily Conserved Function of Proliferating Cell Nuclear Antigen for Cdt1 Degradation by the Cul4-Ddb1 Ubiquitin Ligase in Response to DNA Damage

4 Jan 2006

Abstract excerpt

The DNA replication licensing factor Cdt1 is degraded by the ubiquitin-proteasome pathway during S phase of the cell cycle, to ensure one round of DNA replication during each cell division and in response to DNA damage to halt DNA replication. Constitutive expression of Cdt1 causes DNA re-replication and is associated with the development of a subset of human non-small cell-lung carcinomas. In mammalian cells,...
