The Ino80 chromatin-remodeling complex restores chromatin structure during UV DNA damage repair
Chromatin structure is modulated during deoxyribonucleic acid excision repair, but how this is achieved is unclear. Loss of the yeast Ino80 chromatin-remodeling complex (Ino80-C) moderately sensitizes cells to ultraviolet (UV) light. In this paper, we show that INO80 acts in the same genetic pathway as nucleotide excision repair (NER) and that the Ino80-C contributes to efficient UV photoproduc...
متن کاملThe Ino80 complex prevents invasion of euchromatin into silent chromatin.
Here we show that the Ino80 chromatin remodeling complex (Ino80C) directly prevents euchromatin from invading transcriptionally silent chromatin within intergenic regions and at the border of euchromatin and heterochromatin. Deletion of Ino80C subunits leads to increased H3K79 methylation and noncoding RNA polymerase II (Pol II) transcription centered at the Ino80C-binding sites. The effect of ...
متن کاملFunction of the INO80 chromatin remodeling complex in DNA replication.
ATP-dependent chromatin remodeling complexes are involved in several nuclear processes. In particular the INO80 remodeling complex is an essential factor during transcription and DNA repair. Recently, several labs have described a novel role for INO80 during DNA replication. Moreover, Falbo et al. have presented evidence linking INO80's activities to the DNA damage tolerance pathways during rep...
متن کاملSnapShot: Chromatin Remodeling: INO80 and SWR1
The INO80 and SWR1 complexes belong to the INO80 subfamily of ATP-dependent chromatin-remodeling complexes. These complexes interact with nucleosomes and remodel chromatin by either sliding nucleosomes along the DNA or exchanging histones within nucleosomes. In doing so, the INO80 and SWR1 complexes promote recruitment of regulatory factors to DNA. Distinct from other subfamilies of chromatin-r...
متن کاملIno80 Chromatin Remodeling Complex Promotes Recovery of Stalled Replication Forks
BACKGROUND Chromatin remodeling complexes facilitate the access of enzymes that mediate transcription, replication or repair of DNA by modulating nucleosome position and/or composition. Ino80 is the DNA-dependent Snf2-like ATPase subunit of a complex whose nucleosome remodeling activity requires actin-related proteins, Arp4, Arp5 and Arp8, as well as two RuvB-like DNA helicase subunits. Budding...
