GenomicsDeterminants of nucleosome organization in primary human cells
Genome-wide maps of nucleosome organization in human CD4+ T-cells, CD8+ T-cells, granulocytes, and from in vitro reconstitution. 8 samples include: nucleosome-bound DNA isolated from primary human CD4+ T-cells, nucleosome bound-DNA isolated from primary human CD8+ T-cells, nucleosome-bound DNA isola...

GenomicsA compendium of nucleosome and transcript profiles reveals determinants of chromatin architecture and transcription [Nuc-Seq]
Nucleosomes in all eukaryotes examined to date adopt a characteristic architecture within genes and play fundamental roles in regulating transcription, yet the identity and precise roles of many of the trans-acting factors responsible for the establishment and maintenance of this organization remain...

TranscriptomicsNucleosome Mapping in S. pombe Centromeres
A key element for defining the centromere identity is the incorporation of a specific histone H3, CENP-A, known as Cnp1p in S. pombe. Previous studies have suggested that functional S. pombe centromeres lack nucleosome arrays and may involve chromatin remodeling as a key step of kinetochore assembl...

TranscriptomicsRegulation of nucleosome landscape and transcription factor binding at enhancers by BRG1
Enhancers of transcription activate transcription via binding of sequence-specific transcription factors to their target sites in chromatin. In this report, we identify GATA1-bound enhancers genome-wide and find a global reorganization of the nucleosomes at these enhancers during differentiation of ...

ProteomicsCharacterisation of two distinct Nucleosome Remodelling and Deacetylase Complex (NuRD) assemblies in embryonic stem cells.
Pluripotency and self-renewal, the defining properties of embryonic stem cells, are brought about by transcriptional programs involving an intricate network of transcription factors and chromatin remodelling complexes. The Nucleosome Remodelling and Deacetylase (NuRD) complex plays a crucial and dyn...

TranscriptomicsThe Fun30 ATP-dependent nucleosome remodeler promotes resection of DNA double-strand break ends
Chromosomal double-strand breaks (DSBs) are resected by 5M-bM-^@M-^Y-nucleases to form 3M-bM-^@M-^Y single-strand DNA (ssDNA) substrates for binding by homologous recombination and DNA damage checkpoint proteins. Two redundant pathways of extensive resection were described both in cells and in vitro...

ProteomicsMultiple roles for PARP1 in ALC1-dependent nucleosome remodeling
XL-MS mass spectrometry analysis Cross-linked peptides were resolved for mass spectrometry analysis using a Dionex UltiMate 3000 RSLnano liquid chromatography system. Peptides were initially loaded from the autosampler onto an Acclaim PepMap 100 C18 LC Trap Cartridge (0.3 mm inside diameter, 5 mm le...

GenomicsBAF250a regulates nucleosome occupancy and histone modification in priming embryonic stem cell differentiation
BAF complex is one major group of chromatin remodeling factors in mammals. However, how BAF regulated nucleosomes and other histone modifications is not clear. Here we delete BAF250a, a major component in esBAF to study the nucleosome and histone changes in ESCs. We find that deletion of BAF250a lea...
