INO80 and γ-H2AX Interaction Links ATP-Dependent Chromatin Remodeling to DNA Damage Repair
(Shen et al., 2000). However, it is not known whether the INO80 complex functions in DNA damage repair Waltham, Massachusetts 02454 directly or indirectly through other mechanisms. Here, we show biochemical and genetic evidence that the INO80 complex is directly involved in DNA repair. The Summary key mechanism is through a specific interaction between the INO80 complex and the DNA damage-While...
متن کاملRecruitment of the INO80 Complex by H2A Phosphorylation Links ATP-Dependent Chromatin Remodeling with DNA Double-Strand Break Repair
The budding yeast INO80 complex is a conserved ATP-dependent nucleosome remodeler containing actin-related proteins Arp5 and Arp8. Strains lacking INO80, ARP5, or ARP8 have defects in transcription. Here we show that these mutants are hypersensitive to DNA damaging agents and to double-strand breaks (DSBs) induced by the HO endonuclease. The checkpoint response and most transcriptional modulati...
متن کاملThe 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 کاملATP-dependent chromatin remodeling and DNA double-strand break repair.
The repair of DNA double-strand breaks (DSBs) is critical for the maintenance of genomic stability. Two pathways for the repair of DBSs, nonhomologous end-joining (NHEJ) and homologous recombination (HR), have evolved in eukaryotes. These pathways, like processes such as transcription and replication, act on DNA that is embedded in nucleosomes. Recent studies have shown that DNA repair, like tr...
متن کاملChromatin Remodeling, DNA Damage Repair and Aging
Cells are constantly exposed to a variety of environmental and endogenous conditions causing DNA damage, which is detected and repaired by conserved DNA repair pathways to maintain genomic integrity. Chromatin remodeling is critical in this process, as the organization of eukaryotic DNA into compact chromatin presents a natural barrier to all DNA-related events. Studies on human premature aging...
