A simple method for generating high-resolution maps of genome wide protein binding

ABSTRACT: Chromatin immunoprecipitation (ChIP) and its derivatives are the main techniques used to determine transcription factor binding sites. However, conventional ChIP with sequencing (ChIP-seq) has problems with poor resolution and newer techniques require significant experimental alterations and complex bioinformatics. Here we build upon our high-resolution crosslinking ChIP-seq (X-ChIP-seq) method and compare it to existing methodologies. By using micrococcal nuclease, which has both endo- and exo-nuclease activity to fragment the chromatin and thereby generate precise protein-DNA footprints, high-resolution X-ChIP-seq achieves single base pair resolution of transcription factor binding. A significant advantage of this protocol is the minimal alteration to the conventional ChIP-seq workflow and simple bioinformatic processing.

Meiotic recombination initiation hotspots in Arabidopsis genes and transposons (H3K4m3 ChIP-seq)

Project description:To investigate the relationship between meiotic recombination initiation and H3K4m3 in Arabidopsis, we generated and sequenced H3K4m3 ChIP libraries from meiotic stage floral buds in wild type, arp6 and met1. To produce high-resolution of H3K4m3 mapping, we used micrococcal nuclease (MNase) to digest chromatins that were cross-linked by formaldehyde for ChIP. This experiment provides for H3K4m3 maps with the resolution of mononucleosomal DNA level (~150 bp).

The Drosophila BEAF Insulator Protein Interacts with the Polybromo Subunit of the PBAP Chromatin Remodeling Complex [PRO-seq]

Project description:We examine the effect of this interaction on gene expression and chromatin structure using precision run-on sequencing (PRO-seq) and micrococcal nuclease sequencing (MNase-seq) after RNAi-mediated knockdown in cultured S2 cells. We examine the effect of the interaction between BEAF and polybromo on gene expression and chromatin structure using precision run-on sequencing (PRO-seq) and micrococcal nuclease sequencing (MNase-seq) after RNAi-mediated knockdown in cultured S2 cells.

High-throughput sequencing reveals a simple model of nucleosome energetics

Project description:We use nucleosome maps obtained by high-throughput sequencing to study sequence specificity of intrinsic histone-DNA interactions. In contrast with previous approaches, we employ an analogy between a classical one-dimensional fluid of finite-size particles in an arbitrary external potential and arrays of DNA-bound histone octamers. We derive an analytical solution to infer free energies of nucleosome formation directly from nucleosome occupancies measured in high-throughput experiments. The sequence-specific part of free energies is then captured by fitting them to a sum of energies assigned to individual nucleotide motifs. We have developed hierarchical models of increasing complexity and spatial resolution, establishing that nucleosome occupancies can be explained by systematic differences in mono- and dinucleotide content between nucleosomal and linker DNA sequences, with periodic dinucleotide distributions and longer sequence motifs playing a secondary role. Furthermore, similar sequence signatures are exhibited by control experiments in which genomic DNA is either sonicated or digested with micrococcal nuclease in the absence of nucleosomes, making it possible that current predictions based on highthroughput nucleosome positioning maps are biased by experimental artifacts.

The ISW1 and CHD1 ATP-dependent chromatin remodelers compete to set nucleosome spacing in vivo

Project description:We addressed the roles of three nucleosome spacing enzymes (ISW1, ISW2 and CHD1) in specifying chromatin organization in S. cerevisiae. Comparison of budding yeast nucleosome positions obtained using micrococcal nuclease digestion followed by paired-end sequencing (MNase-seq). We sequenced nucleosomes from isogenic strains with the isw1Î, isw2Î or chd1Î mutations in all combinations. We measured gene activity by ChIP-seq for the Rpb3 subunit of RNA polymerase II for some of these mutants.

Epigenome characterization at single base-pair resolution

Project description:We have combined standard micrococcal (MNase) digestion of nuclei with a modified protocol for construction paired-end DNA sequencing libraries to map both nucleosomes and subnucleosome-sized particles at single base-pair resolution throughout the budding yeast genome. We found that partially unwrapped nucleosomes and subnucleosome-sized particles can occupy the same position within a cell population, suggesting dynamic behavior. By varying the time of MNase digestion, we have been able to observe changes that reflect differential sensitivity of particles, including eviction of nucleosomes. Our protocol and mapping method provide a general strategy for characterizing full epigenomes. We used micrococcal nuclease mapping, chromatin immunoprecipitation and paired-end sequencing to determine the structure of yeast centromeres at single base-pair resolution.
