Abstract:
ATP-dependent nucleosome remodelers use ATP hydrolysis to shift, evict and exchange histone dimers or octamers and have well-established roles in transcription. Earlier work has suggested a role for nucleosome remodelers such as INO80 in double-strand break (DSB) repair. This review will begin with an update on recent studies that explore how remodelers are recruited to DSBs. We then examine their impact on various steps of repair, focusing on resection and the formation of the Rad51-ssDNA nucleofilament. Finally, we will explore new studies that implicate remodelers in the physical movement of chromatin in response to damage.

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...
