Abstract:
Eukaryotic cells repair ultraviolet light (UV)- and chemical carcinogen-induced DNA strand-distorting damage through the nucleotide excision repair (NER) pathway. Concurrent activation of the DNA damage checkpoints is also required to arrest the cell cycle and allow time for NER action. Recent studies uncovered critical roles for ubiquitin-mediated post-translational modifications in controlling both NER and checkpoint functions. In this review, we will discuss recent progress in delineating the roles of cullin-RING E3 ubiquitin ligases in orchestrating the cellular DNA damage response through ubiquitination of NER factors, histones, and checkpoint effectors.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
