Altering nucleosomes during DNA double-strand break repair in yeast

Trends Genet 22(12):7 (2006) PMID 16997415

Although chromatin remodeling has a key role in the regulation of gene expression, it is also important for other chromatin-based processes such as DNA repair, replication and recombination. ATP-dependent chromatin remodeling factors have unique roles in disrupting histone-DNA interactions and are targeted to gene promoters to 'loosen' chromatin for access of transcription factors. Recently, three chromatin remodeling factors with roles in transcriptional regulation have also been shown to be present at sites of DNA double-strand breaks (DSBs) in yeast. These factors control different aspects of DSB repair, suggesting that chromatin remodeling constitutes a key mechanism to preserve genome integrity.

    We will review these mechanisms and describe the state of knowledge about the proteins involved. However, we will also consider an additional layer of complexity. The DNA in the cell is packaged with histone proteins into chromatin. Chromatin structure provides an additional layer of heritable infor...

    Assembly, mobilization and disassembly of nucleosomes can influence the regulation of gene expression and other processes that act on eukaryotic DNA. Distinct nucleosome-assembly pathways deposit dimeric subunits behind the replication fork or at sites of active processes that mobilize pre-existing...

    In eukaryotic cells DNA is associated with proteins to form a complex known as chromatin. The dominant proteins within this chromatin complex are the histones, which are subject to a wide variety of covalent and reversible posttranslational modifications such as acetylation. A specialized family of...
