Chemical modifications of histones can mediate diverse DNA-templated processes, including gene transcription<sup>1-3</sup>. Here we provide evidence for a class of histone post-translational modification, serotonylation of glutamine, which occurs at position 5 (Q5ser) on histone H3 in organisms that produce serotonin (also known as 5-hydroxytryptamine (5-HT)). We demonstrate that tissue transglutaminase 2 can serotonylate histone H3 tri-methylated lysine 4 (H3K4me3)-marked nucleosomes, resulting ...[more]

Histone serotonylation is a permissive modification that enhances TFIID binding to H3K4me3.

Project description:Chemical modifications of histones can mediate diverse DNA-templated processes, including gene transcription1-3. Here we provide evidence for a class of histone post-translational modification, serotonylation of glutamine, which occurs at position 5 (Q5ser) on histone H3 in organisms that produce serotonin (also known as 5-hydroxytryptamine (5-HT)). We demonstrate that tissue transglutaminase 2 can serotonylate histone H3 tri-methylated lysine 4 (H3K4me3)-marked nucleosomes, resulting in the presence of combinatorial H3K4me3Q5ser in vivo. H3K4me3Q5ser displays a ubiquitous pattern of tissue expression in mammals, with enrichment observed in brain and gut, two organ systems responsible for the bulk of 5-HT production. Genome-wide analyses of human serotonergic neurons, developing mouse brain and cultured serotonergic cells indicate that H3K4me3Q5ser nucleosomes are enriched in euchromatin, are sensitive to cellular differentiation and correlate with permissive gene expression, phenomena that are linked to the potentiation of TFIID4-6 interactions with H3K4me3. Cells that ectopically express a H3 mutant that cannot be serotonylated display significantly altered expression of H3K4me3Q5ser-target loci, which leads to deficits in differentiation. Taken together, these data identify a direct role for 5-HT, independent from its contributions to neurotransmission and cellular signalling, in the mediation of permissive gene expression.

Cse4 ChIP-chip

Project description:In order to take an unbiased approach and discover all the locations of Cse4 in the genome, we utilized formaldehyde crosslinking and immunoprecipitation followed by hybridization to DNA microarrays. We analyzed the location of Cse4 in three different strains; one in which the endogenous Cse4 is tagged with 12Myc epitopes (Cse4-12Myc), and one which contained both the endogenous Cse4 (untagged) and an ectopic copy of Cse4-12Myc expressed from the GAL1-10 promoter (pGAL1-10-Cse4-12Myc), and one in which Cse4 is tagged with 3HA epitopes (Cse4-3HA). ChIP-chip was performed using custom microarrays, to look at the genome-wide localization of the centromeric histone variant Cse4. Biological replicates were performed for each Cse4 epitope-tagged strain

BiTS Chromatin Immunoprecipitation of H3K4me3 and H3K27ac in Drosophila melanogaster differentiating cardiomyocytes

Project description:Here we improved BiTS-ChIP (Bonn et al, Nature Protocols 7, 978-994 (2012)) to identify active enhancer and promoter elements genome wide in the 104 cardiomyocytes that constitute the Drosophila heart tube and represents only ~0.5% of the total cell content of the embryo. A transgenic Drosophila strain expressing nuclear GFP under the control of a cardiac specific enhancer (TinC*>GFP) was used for staged embryo collections at stages 13-14 (10-13h of development). After embryo fixation and dissociation, intact fixed nuclei were fluorescent labelling. Purification of this rare nuclear population was achieved by a two-step sorting procedure, yielding ~98% purity. Chromatin was extracted and used for immunoprecipitation and sequencing (ChIP-seq) to analyze chromatin modifications at promoters (H3K4me3 and H3K27ac) and enhancers (H3K27ac). Two independent biological replicates (from FACS sorting, chromatin preparations and ChIP-Seq) were performed for each mark and sequenced using Illumina HiSeq.

Genome-wide maps of WT and over-expressing CenH3/CENP-A in Human HeLa S3 cells

Project description:Centromeres are essential to ensure proper chromosome segregation in eukaryotes. Their definition relies on the presence of a centromere-specific H3 histone variant CenH3, known as CENP-A in mammals. Its overexpression in aggressive cancers raises questions concerning its effect on chromatin dynamics and contribution to tumorigenesis. We find that CenH3 overexpression in human cells leads to ectopic enrichment at sites of active histone turnover. Furthermore, in over-expressing conditions, we see the formation of a novel heterotypic particle (CenH3-H4/H3.3-H4) that occludes CTCF binding, but this occlusion has only a minor effect on gene expression. Ectopic localization and CTCF occlusion depends on the H3.3 chaperone DAXX, rather than its dedicated chaperone HJURP. This DAXX-dependent occlusion also occurs in naturally overexpressing cancer cells. Furthermore, our cellular model reveals a DAXX-dependent survival advantage when challenged by DNA damage. Our findings illustrate how changes in histone variant levels can disrupt chromatin dynamics in disease and provides a possible mechanism for cell resistance to anti-cancer treatments. Examination of CenH3 ChIP-seq and RNA-seq transcriptional programs in two conditions - WT and CenH3 over-expressing.

ChIP-seq of E. coli to identify H-NS and Fis binding at multiple time-points during growth in rich medium

Project description:Among the most important regulators of gene expression in bacteria are 'nucleoid-associated proteins'. These proteins alter the topology of the bound DNA by bending, wrapping or bridging it, thus having multiple effects, including transcriptional regulation, on the bacterial cell. Among the best-studied nucleoid proteins are H-NS and Fis, which bind to specific sequences on the DNA. H-NS is a global repressor of gene expression. Fis alters the global conformation of the DNA by introducing branched structures in it; but its effect on gene expression on a genomic scale remains largely unclear.<br><br>Several bacterial transcriptional regulators including H-NS and Fis have been studied using ChIP-chip. However, the higher resolution and dynamic range offered by ChIP-Seq have not been exploited for any bacterial species. By performing ChIP-Seq of these two proteins, we present the first such study in a bacterium. In addition to providing a proof-of-principle for the use of this technology for bacteria, we perform our study at multiple time-points during growth in rich medium, thus generating new insights into how these proteins function under different cellular conditions. Further, by analysing our data in conjunction with newly-generated gene expression and RNA polymerase-chromosome interaction data we provide new interpretation of the genome-scale patterns of the interactions of these proteins to the DNA.

BS3 crosslinking of GRC3 and Las1

Project description:Ribosome assembly is a complex process involving the coordination of multiple enzymes. A recently discovered endoribonuclease (RNase), Las1, and the poly-nucleotide kinase (PNK), Grc3, assemble into a complex. To attempt to understand the coordination of the two enzymes in this complex, we performed chemical crosslinking and mass spectrometry and also solved a series of cryo-electron microscopy structures of RNase PNK in multiple conformational states.

Chromatin immunoprecipitation of ectopic FLAG-tagged TCF7L1 followed by Mass Spectrome-try in H9-TCF7L1 Human Embryonic Stem Cells

Project description:TCF7L1 is a member of the T cell factor/Lymphoid enhancer factor (TCF/LEF) family of tran-scription factors that are part of the WNT/beta-CATENIN signaling pathway. TCF7L1 modulates transcription by interacting with other regulators on chromatin. TCF7L1 has been shown to be one of the key factors in maintaining pluripotency in human embryonic stem cells (ESCs). We previously demonstrated that the absence of TCF71 causes H9 hESCs to differentiate sponta-neously (Sierra et al., 2018 Development 145(4).pii:dev161075). Mechanistically, how TCF7L1 inhibits differentiation and keeps cells in the pluripotent state is not clear. Identifying transcrip-tional regulators on chromatin is a critical step to elucidating one of several molecular mecha-nisms controlled by TCF7L1. We previously developed a FLAG tagged TCF7L1 transgene that is controlled by a doxycycline-inducible TET-ON system and generated the H9-TCF7L1 line (Sier-ra et al., 2018 Development 145(4).pii:dev161075). Here we used the H9-TCF7L1 line and em-ployed the method called rapid immunoprecipitation (IP) mass spectrometry of endogenous pro-tein (RIME) (Mohammed et al., 2016 Nat Protoc 11(2):316-26) to identify TCF7L1-associated proteins on chromatin. Coupling of these two methods (the FLAG tagged TETON inducible sys-tem and RIME) allowed us to control the level of TCF7L1 expression in hESCs, immunopreci-pate TCF7L1 using an anti-FLAG antibody and capture TCF7L1-bound associated complexes on chromatin. Our MS analysis identified some known proteins that have been shown to associate with the WNT/beta-CATENIN/TCF/LEF pathway, as well as novel complexes that have not been linked with TCF7L1. Gene Ontology analysis suggest these proteins function in chromatin modi-fication, splicing, and RNA processing. Our data could create new ideas for in-depth studies of TCF7L1 controlling pluripotency in human ESCs and for understanding how TCF7L1 may act in other cell types.
