Mechanisms and functions of ATP-dependent chromatin-remodeling enzymes.

ABSTRACT: 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-remodeling activities may have emerged by adaptation of ancient DNA translocases to respond to specific features of chromatin. Here, we discuss such evidence and also relate mechanistic insights to our understanding of how chromatin-remodeling enzymes enable different in vivo processes.

Replication-Coupled Nucleosome Assembly and Positioning by ATP-Dependent Chromatin-Remodeling Enzymes.

Project description:During DNA replication, chromatin must be disassembled and faithfully reassembled on newly synthesized genomes. The mechanisms that govern the assembly of chromatin structures following DNA replication are poorly understood. Here, we exploited Okazaki fragment synthesis and other assays to study how nucleosomes are deposited and become organized in S. cerevisiae. We observe that global nucleosome positioning is quickly established on newly synthesized DNA in vivo. Importantly, we find that ATP-dependent chromatin-remodeling enzymes, Isw1 and Chd1, collaborate with histone chaperones to remodel nucleosomes as they are loaded behind a replication fork. Using a whole-genome sequencing approach, we determine that the positioning of newly deposited nucleosomes in vivo is specified by the combined actions of ATP-dependent chromatin-remodeling enzymes and select DNA-binding proteins. Altogether, our data provide in vivo evidence for coordinated "loading and remodeling" of nucleosomes behind the replication fork, allowing for rapid organization of chromatin during S phase.

Replication-coupled nucleosome assembly and positioning by ATP-dependent chromatin remodeling enzymes

Project description:We have previously shown that Okazaki fragments in Saccharomyces cerevisiae are sized according to the chromatin repeat. Here we demonstrate that nucleosome positioning is rapidly established on newly synthesized DNA. Using deep sequencing, we demonstrate that ATP-dependent chromatin remodeling enzymes, Isw1 and Chd1, collaborate with histone chaperones, such as CAF-1 and Rtt106, to remodel nucleosomes, as they are loaded. Importantly, we find that nucleosome positioning is ultimately specified by select sequence-specific DNA-binding factors, which serve as physical cues for chromatin remodeling. Our results provide a mechanistic understanding of how chromatin structures are replicated in vivo, and show that chromatin structure at gene promoters is rapidly established after DNA replication. Altogether, our data provide evidence for coordinated âloading and remodelingâ of nucleosomes behind the replication fork, in collaboration with packing of nucleosomes against a barrier. 7 samples, including a wild type, are included. All are single-end sequenced via Ion Torrent PGM methodology.

The ATP-dependent chromatin remodeling enzymes CHD6, CHD7, and CHD8 exhibit distinct nucleosome binding and remodeling activities.

Project description:Proper chromatin regulation is central to genome function and maintenance. The group III chromodomain-helicase-DNA-binding (CHD) family of ATP-dependent chromatin remodeling enzymes, comprising CHD6, CHD7, CHD8, and CHD9, has well-documented roles in transcription regulation, impacting both organism development and disease etiology. These four enzymes are similar in their constituent domains, but they fill surprisingly non-redundant roles in the cell, with deficiencies in individual enzymes leading to dissimilar disease states such as CHARGE syndrome or autism spectrum disorders. The mechanisms explaining their divergent, non-overlapping functions are unclear. In this study, we performed an in-depth biochemical analysis of purified CHD6, CHD7, and CHD8 and discovered distinct differences in chromatin remodeling specificities and activities among them. We report that CHD6 and CHD7 both bind with high affinity to short linker DNA, whereas CHD8 requires longer DNA for binding. As a result, CHD8 slides nucleosomes into positions with more flanking linker DNA than CHD7. Moreover, we found that, although CHD7 and CHD8 slide nucleosomes, CHD6 disrupts nucleosomes in a distinct non-sliding manner. The different activities of these enzymes likely lead to differences in chromatin structure and, thereby, transcriptional control, at the enhancer and promoter loci where these enzymes bind. Overall, our work provides a mechanistic basis for both the non-redundant roles and the diverse mutant disease states of these enzymes in vivo.

ATP-dependent chromatin remodeling during mammalian development.

Project description:Precise gene expression ensures proper stem and progenitor cell differentiation, lineage commitment and organogenesis during mammalian development. ATP-dependent chromatin-remodeling complexes utilize the energy from ATP hydrolysis to reorganize chromatin and, hence, regulate gene expression. These complexes contain diverse subunits that together provide a multitude of functions, from early embryogenesis through cell differentiation and development into various adult tissues. Here, we review the functions of chromatin remodelers and their different subunits during mammalian development. We discuss the mechanisms by which chromatin remodelers function and highlight their specificities during mammalian cell differentiation and organogenesis.

Recombinational repair within heterochromatin requires ATP-dependent chromatin remodeling.

Project description: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 vitro. We find that addition of Sir3p to a nucleosomal substrate is sufficient to eliminate yRad51p-catalyzed formation of joints, and that this repression is enhanced by Sir2p/Sir4p. Importantly, Sir-mediated repression requires histone residues that are critical for silencing in vivo. Moreover, we demonstrate that the SWI/SNF chromatin-remodeling enzyme facilitates joint formation by evicting Sir3p, thereby promoting subsequent Rad54p-dependent formation of a strand invasion product. These results suggest that recombinational repair in the context of heterochromatin presents additional constraints that can be overcome by ATP-dependent chromatin-remodeling enzymes.

ATP-dependent chromatin remodeling shapes the DNA replication landscape.

Project description:The eukaryotic DNA replication machinery must traverse every nucleosome in the genome during S phase. As nucleosomes are generally inhibitory to DNA-dependent processes, chromatin structure must undergo extensive reorganization to facilitate DNA synthesis. However, the identity of chromatin-remodeling factors involved in replication and how they affect DNA synthesis is largely unknown. Here we show that two highly conserved ATP-dependent chromatin-remodeling complexes in Saccharomyces cerevisiae, Isw2 and Ino80, function in parallel to promote replication fork progression. As a result, Isw2 and Ino80 have especially important roles for replication of late-replicating regions during periods of replication stress. Both Isw2 and Ino80 complexes are enriched at sites of replication, suggesting that these complexes act directly to promote fork progression. These findings identify ATP-dependent chromatin-remodeling complexes that promote DNA replication and define a specific stage of replication that requires remodeling for normal function.

Distinct roles for ATP-dependent chromatin remodeling enzymes in nucleotide excision repair in yeast

Project description:Nucleosomes are a significant barrier to the repair of UV damage because they impede damage recognition by nucleotide excision repair (NER). The RSC and SWI/SNF chromatin remodelers function in cells to promote DNA access by moving or evicting nucleosomes and both have been linked to NER in yeast. Here, we report genome-wide repair maps of UV-induced cyclobutane pyrimidine dimers (CPDs) in yeast cells lacking RSC or SWI/SNF activity. Our data indicate that SWI/SNF is not generally required for NER, but instead promotes repair of CPD lesions at specific yeast genes. In contrast, mutation or depletion of RSC subunits causes a general defect in NER across the yeast genome. Our data indicate that RSC is required for repair not only in nucleosomal DNA, but also neighboring linker DNA and nucleosome-free regions (NFRs). Furthermore, our data indicate that RSC plays a direct role in transcription coupled-NER (TC-NER) of transcribed DNA. These findings help to define the specific genomic and chromatin contexts in which each chromatin remodeler functions in DNA repair, and indicate that RSC plays a unique function in facilitating repair by both NER subpathways.

Molecular architecture of the ATP-dependent chromatin-remodeling complex SWR1.

Project description:The ATP-dependent chromatin-remodeling complex SWR1 exchanges a variant histone H2A.Z/H2B dimer for a canonical H2A/H2B dimer at nucleosomes flanking histone-depleted regions, such as promoters. This localization of H2A.Z is conserved throughout eukaryotes. SWR1 is a 1 megadalton complex containing 14 different polypeptides, including the AAA+ ATPases Rvb1 and Rvb2. Using electron microscopy, we obtained the three-dimensional structure of SWR1 and mapped its major functional components. Our data show that SWR1 contains a single heterohexameric Rvb1/Rvb2 ring that, together with the catalytic subunit Swr1, brackets two independently assembled multisubunit modules. We also show that SWR1 undergoes a large conformational change upon engaging a limited region of the nucleosome core particle. Our work suggests an important structural role for the Rvbs and a distinct substrate-handling mode by SWR1, thereby providing a structural framework for understanding the complex dimer-exchange reaction.

ATP-dependent chromatin remodeling shapes the long noncoding RNA landscape.

Project description:Long noncoding RNAs (lncRNAs) are pervasively transcribed across eukaryotic genomes, but functions of only a very small subset of them have been demonstrated. This has led to active debate about whether many of them have any biological functions. In addition, very few regulators of lncRNAs have been identified. We developed a novel genetic screen using reconstituted RNAi in Saccharomyces cerevisiae and systematically identified a large number of putative lncRNA repressors. Among them, we found that four highly conserved chromatin remodeling factors are global lncRNA repressors that play major roles in shaping the eukaryotic lncRNA transcriptome. Importantly, we identified >250 antisense lncRNAs (CRRATs [chromatin remodeling-repressed antisense transcripts]) whose repression by these chromatin remodeling factors is required for the maintenance of normal levels of overlapping mRNA transcripts. Our results strongly suggest that regulation of mRNA through repression of antisense lncRNAs is far more broadly used than previously appreciated.
