The Emerging Roles of ATP-Dependent Chromatin Remodeling Enzymes in Nucleotide Excision Repair
DNA repair in eukaryotic cells takes place in the context of chromatin, where DNA, including damaged DNA, is tightly packed into nucleosomes and higher order chromatin structures. Chromatin intrinsically restricts accessibility of DNA repair proteins to the damaged DNA and impacts upon the overall rate of DNA repair. Chromatin is highly responsive to DNA damage and undergoes specific remodeling...
متن کاملMechanisms and Functions of ATP-Dependent Chromatin-Remodeling Enzymes
Chromatin provides both a means to accommodate a large amount of genetic material in a small space and a means to package the same genetic material in different chromatin states. Transitions between chromatin states are enabled by chromatin-remodeling ATPases, which catalyze a diverse range of structural transformations. Biochemical evidence over the last two decades suggests that chromatin-rem...
متن کاملATP-dependent chromatin remodeling enzymes and their various roles in cell cycle control.
The modification of chromatin structure by various mechanisms has emerged as a key regulatory component of nuclear programs. Cell cycle progression and exit are affected by the integrity of chromatin architecture as well as by regulatory cues that chromatin structure imposes on the expression of cell cycle genes. ATP-dependent chromatin remodeling factors use the energy derived from ATP-hydroly...
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 کاملRecombinational Repair within Heterochromatin Requires ATP-Dependent Chromatin Remodeling
Heterochromatin plays a key role in protection of chromosome integrity by suppressing homologous recombination. In Saccharomyces cerevisiae, Sir2p, Sir3p, and Sir4p are structural components of heterochromatin found at telomeres and the silent mating-type loci. Here we have investigated whether incorporation of Sir proteins into minichromosomes regulates early steps of recombinational repair in...
