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.
