JASPer controls interphase histone H3S10 phosphorylation by chromosomal kinase JIL-1 in Drosophila. Nat Commun 2019; 10:5343.

Abstract
In flies, the chromosomal kinase JIL-1 is responsible for most interphase histone H3S10 phosphorylation and has been proposed to protect active chromatin from acquiring heterochromatic marks, such as dimethylated histone H3K9 (H3K9me2) and HP1. Here, we show that JIL-1's targeting to chromatin depends on a PWWP domain-containing protein JASPer (JIL-1 Anchoring and Stabilizing Protein). JASPer-JIL-1 (JJ)-complex is the major form of kinase in vivo and is targeted to active genes and telomeric transposons via binding of the PWWP domain of JASPer to H3K36me3 nucleosomes, to modulate transcriptional output. JIL-1 and JJ-complex depletion in cycling cells lead to small changes in H3K9me2 distribution at active genes and telomeric transposons. Finally, we identify interactors of the endogenous JJ-complex and propose that JIL-1 not only prevents heterochromatin formation but also coordinates chromatin-based regulation in the transcribed part of the genome.

Abstract
The mitogen- and stress-activated protein kinases activated by the extracellular-signal-regulated kinase 1/2 and/or stress-activated protein kinase 2/p38 mitogen-activated protein kinase pathways are recruited to the regulatory region of a subset of genes termed immediate-early genes, often leading to their induction. These genes, many of which code for transcription factors, have been directly linked to the phenotypic events in carcinogenesis. In this paper, we focus on the mitogen- and stress-activated protein kinases; their discovery, activation, H3 phosphorylation and recent discoveries in their roles in cancer.

Abstract
BACKGROUND Photoageing is attributed to continuous sunlight or artificial ultraviolet exposure and manifests as clinical and histological changes in skin. Epigenetic changes have been found to be involved in the pathogenesis of photoageing. However, the underlying mechanisms are unclear. OBJECTIVES To analyse histone modification patterns in sun-exposed and nonexposed skin, and to identify the abnormally histone-modified genes related to photoageing. METHODS Skin biopsies were collected from both the outer forearm (sun-exposed area) and the buttock (sun-protected area) in 20 healthy middle-aged female volunteers. Global histone H3/H4 acetylation and H3K4/H3K9 methylation statuses were assessed by enzyme-linked immunosorbent assay. Expression levels of histone acetyltransferases and histone deacetylases were measured by reverse-transcriptase quantitative polymerase chain reaction (qPCR) and Western blot. Chromatin immunoprecipitation combined with DNA microarray (ChIP-chip) assay with anti-acetyl-histone H3 antibody in a sun-exposed pool (combining six sun-exposed skin samples) and a nonexposed pool (combining six nonexposed skin samples) was conducted to explore the abnormally acetylated histone H3 genes related to photoageing; ChIP-qPCR was then used to verify the results of ChIP-chip. RESULTS We observed higher global histone H3 acetylation levels increased EP300 and decreased HDAC1 and SIRT1 expression in sun-exposed skin compared with matched nonexposed skin. Furthermore, the ChIP-chip assay showed that 227 genes displayed significant hyperacetylation of histone H3, and 81 genes displayed significant hypoacetylation of histone H3 between the two groups. Histone H3 acetylation levels on the promoters of PDCD5, ITIH5, MMP1 and AHR were positively correlated with the mRNA expression of the corresponding gene. CONCLUSIONS Chronic sun exposure-induced histone H3 hyperacetylation may play a critical role in the pathogenesis of skin photoageing.

Abstract
Phosphorylation of histone H3 at serine 10 (H3S10ph) by Aurora kinases plays an important role in mitosis; however, H3S10ph also marks regulatory regions of inducible genes in interphase mammalian cells, implicating mitosis-independent functions. Using the fluorescent ubiquitin-mediated cell cycle indicator (FUCCI), we found that 30% of the genome in interphase mouse embryonic stem cells (ESCs) is marked with H3S10ph. H3S10ph broadly demarcates gene-rich regions in G1 and is positively correlated with domains of early DNA replication timing (RT) but negatively correlated with H3K9me2 and lamin-associated domains (LADs). Consistent with mitosis-independent kinase activity, this pattern was preserved in ESCs treated with Hesperadin, a potent inhibitor of Aurora B/C kinases. Disruption of H3S10ph by expression of nonphosphorylatable H3.3S10A results in ectopic spreading of H3K9me2 into adjacent euchromatic regions, mimicking the phenotype observed in Drosophila JIL-1 kinase mutants. Conversely, interphase H3S10ph domains expand in Ehmt1 (also known as Glp) null ESCs, revealing that H3S10ph deposition is restricted by H3K9me2. Strikingly, spreading of H3S10ph at RT transition regions (TTRs) is accompanied by aberrant transcription initiation of genes co-oriented with the replication fork in Ehmt1-/- and Ehmt2-/- ESCs, indicating that establishment of repressive chromatin on the leading strand following DNA synthesis may depend upon these lysine methyltransferases. H3S10ph is also anti-correlated with H3K9me2 in interphase murine embryonic fibroblasts (MEFs) and is restricted to intragenic regions of actively transcribing genes by EHMT2. Taken together, these observations reveal that H3S10ph may play a general role in restricting the spreading of repressive chromatin in interphase mammalian cells.

Abstract
Post-translational chromatin modifications are an important regulatory mechanism in light signalling and circadian clock function. The regulation of diurnal transcript level changes requires fine-tuning of the expression of generally active genes depending on the prevailing environmental conditions. We investigated the association of histone modifications H3K4me3, H3K9ac, H3K9me2, H3S10p, H3K27ac, H3K27me3 and H3S28p with diurnal changes in transcript expression using chromatin immunoprecipitations followed by sequencing (ChIP-Seq) in fully expanded leaves 6 of Arabidopsis thaliana grown in short-day optimal and water-deficit conditions. We identified a differential H3K9ac, H3K27ac and H3S28p signature between end-of-day and end-of-night that is correlated with changes in diurnal transcript levels. Genes with this signature have particular over-represented promoter elements and encode proteins that are significantly enriched for transcription factors, circadian clock and starch catabolic process. Additional activating modifications were prevalent in optimally watered (H3S10p) and in water-deficit (H3K4me3) plants. The data suggest a mechanism for diurnal transcript level regulation in which reduced binding of repressive transcription factors facilitates activating H3K9ac, H3K27ac and H3S28p chromatin modifications. The presence of activating chromatin modification patterns on genes only at times of the day when their expression is required can explain why some genes are differentially inducible during the diurnal cycle.

Abstract
Eukaryotic chromatin is a complex and dynamic system in which the DNA double helix is organized and protected by interactions with histone proteins. This system is regulated through a large network of dynamic post-translational modifications (PTMs) which ensure proper gene transcription, DNA repair, and other processes involving DNA. Homogenous protein samples with precisely characterized modification sites are necessary to understand better the functions of modified histone proteins. Here, we discuss sets of chemical and biological tools developed for the preparation of modified histones, with a focus on the appropriate choice of tool for a given target. We start with genetic approaches for the creation of modified histones, including the incorporation of genetic mimics of histone modifications, chemical installation of modification analogs, and the use of the expanded genetic code to incorporate modified amino acids. We also cover the chemical ligation techniques which have been invaluable in the generation of complex modified histones indistinguishable from their natural counterparts. We end with a prospectus on future directions.

Abstract
Patterns of histone post-translational modifications (PTMs) and DNA modifications establish a landscape of chromatin states with regulatory impact on gene expression, cell differentiation and development. These diverse modifications are read out by effector protein complexes, which ultimately determine their functional outcome by modulating the activity state of underlying genes. From genome-wide studies employing high-throughput ChIP-Seq methods as well as proteomic mass spectrometry studies, a large number of PTMs are known and their coexistence patterns and associations with genomic regions have been mapped in a large number of different cell types. Conversely, the molecular interplay between chromatin effector proteins and modified chromatin regions as well as their resulting biological output is less well understood on a molecular level. Within the last decade a host of chemical approaches has been developed with the goal to produce synthetic chromatin with a defined arrangement of PTMs. These methods now permit systematic functional studies of individual histone and DNA modifications, and additionally provide a discovery platform to identify further interacting nuclear proteins. Complementary chemical- and synthetic-biology methods have emerged to directly observe and modulate the modification landscape in living cells and to readily probe the effect of altered PTM patterns on biological processes. Herein, we review current methodologies allowing chemical and synthetic biological engineering of distinct chromatin states in vitro and in vivo with the aim of obtaining a molecular understanding of histone and DNA modification function. This article is part of a Special Issue entitled: Molecular mechanisms of histone modification function.

Abstract
Systematic analysis of histone modifications has revealed a plethora of posttranslational modifications that mediate changes in chromatin structure and gene expression. Histone phosphorylation is a transient histone modification that becomes induced by extracellular signals, DNA damage or entry into mitosis. Importantly, phosphorylation of histone proteins does lead not only to the binding of specific reader proteins but also to changes in the affinity for readers or writers of other histone modifications. This induces a cross-talk between different chromatin modifications that allows the spatio-temporal control of chromatin-associated events. In this review we will summarize the progress in our current knowledge of factors sensing reversible histone phosphorylation in different biological scenarios. This article is part of a Special Issue entitled: Molecular mechanisms of histone modification function. Signal induced histone phosphorylation is associated with local chromatin opening and transcriptional activation. Histone phosphorylation is also linked with chromatin condensation during mitosis. Histone phosphorylation marks are important for regulation of the DNA damage response. Specific reader proteins recognize histone phosphorylation marks alone or in combination with other histone modifications. Histone phosphorylation affects the affinity of readers or writers of other histone modifications.

Abstract
Posttranslational modifications (PTMs) of chromatin are involved in gene regulation, thereby contributing to cell differentiation, lineage determination, and organism development. Discrete chromatin states are established by the action of a large set of enzymes that catalyze the deposition, propagation, and removal of histone PTMs, thereby modulating gene expression. Given their central role in determining and maintaining cellular phenotype, as well as in controlling chromatin processes such as DNA repair, the dysregulation of these enzymes can have serious consequences, and can result in cancer and neurodegenerative diseases. Thus, such chromatin regulator proteins are promising drug targets. However, they are often present in large, modular protein complexes that specifically recognize target chromatin regions and exhibit intricate regulation through preexisting histone marks. This renders the study of their enzymatic mechanisms complex. Recent developments in the chemical production of defined chromatin substrates show great promise for improving our understanding of the activity of chromatin regulator complexes at the molecular level. Herein I discuss examples highlighting the application of synthetic chromatin to study the enzymatic mechanisms and regulatory pathways of these crucial protein complexes in detail, with potential implications for assay development in pharmacological research.

Abstract
Metaphase chromosomes are visible hallmarks of mitosis, yet our understanding of their structure and of the forces shaping them is rudimentary. Phosphorylation of histone H3 serine 10 (H3 S10) by Aurora B kinase is a signature event of mitosis, but its function in chromatin condensation is unclear. Using genetically encoded ultraviolet light-inducible cross-linkers, we monitored protein-protein interactions with spatiotemporal resolution in living yeast to identify the molecular details of the pathway downstream of H3 S10 phosphorylation. This modification leads to the recruitment of the histone deacetylase Hst2p that subsequently removes an acetyl group from histone H4 lysine 16, freeing the H4 tail to interact with the surface of neighboring nucleosomes and promoting fiber condensation. This cascade of events provides a condensin-independent driving force of chromatin hypercondensation during mitosis.

Abstract
Phosphorylation of Ser10 of histone H3 regulates chromosome condensation and transcriptional activity. Using time-resolved, high-resolution NMR spectroscopy, we demonstrate that histone H3 Ser10 phosphorylation inhibits checkpoint kinase 1 (Chk1)- and protein kinase C (PKC)-mediated modification of Thr11 and Thr6, the respective primary substrate sites of these kinases. On unmodified H3, both enzymes also target Ser10 and thereby establish autoinhibitory feedback states on individual H3 tails. Whereas phosphorylated Ser10 does not affect acetylation of Lys14 by Gcn5, phosphorylated Thr11 impedes acetylation. Our observations reveal mechanistic hierarchies of H3 phosphorylation and acetylation events and provide a framework for intramolecular modification cross-talk within the N terminus of histone H3.

Abstract
Although discovered long ago, posttranslational phosphorylation of histones has been in the spotlight only recently. Information is accumulating almost daily on phosphorylation of histones and their roles in cellular physiology and human diseases. An extensive cross talk exists between phosphorylation and other posttranslational modifications, which together regulate various biological processes, including gene transcription, DNA repair, and cell cycle progression. Recent research on histone phosphorylation has demonstrated that nearly all histone types are phosphorylated at specific residues and that these modifications act as a critical intermediate step in chromosome condensation during cell division, transcriptional regulation, and DNA damage repair. As with all young fields, apparently conflicting and sometimes controversial observations about histone phosphorylations and their true functions in different species are found in the literature. Accumulating evidence suggests that instead of functioning strictly as part of a general code, histone phosphorylation probably functions by establishing cross talk with other histone modifications and serving as a platform for recruitment or release of effector proteins, leading to a downstream cascade of events. Here we extensively review published information on the complexities of histone phosphorylation, the roles of proteins recognizing these modifications and the resuting physiological outcome, and, importantly, future challenges and opportunities in this fast-moving field.

Abstract
Chromatin condensation and subsequent decondensation are processes required for proper execution of various cellular events. During mitosis, chromatin compaction is at its highest, whereas relaxation of chromatin is necessary for DNA replication, repair, recombination, and gene transcription. Since histone proteins are directly complexed with DNA in the form of a nucleosome, great emphasis is put on deciphering histone post-translational modifications that control the chromatin condensation state. Histone H3 phosphorylation is a mark present in mitosis, where chromatin condensation is necessary, and in transcriptional activation of genes, when chromatin needs to be decondensed. There are four characterized phospho residues within the H3 N-terminal tail during mitosis: Thr3, Ser10, Thr11, and Ser28. Interestingly, H3 phosphorylated at Ser10, Thr11, and Ser28 has been observed on genomic regions of transcriptionally active genes. Therefore, H3 phosphorylation is involved in processes requiring opposing chromatin states. The level of H3 phosphorylation is mediated by opposing actions of specific kinases and phosphatases during mitosis and gene transcription. The cellular contexts under which specific residues on H3 are phosphorylated in mitosis and interphase are known to some extent. However, the functional consequences of H3 phosphorylation are still unclear.

Abstract
Bromodomains are acetyl lysine binding modules found in many complexes that regulate gene transcription. In budding yeast, the coactivator complex SAGA (Spt-Ada-Gcn5-acetyl-transferase) predominantly facilitates transcription of stress-activated genes and requires the bromodomain of the Gcn5 subunit for full activation of a number of these genes. This bromodomain has previously been shown to promote retention of the complex to H3 and H4 acetylated nucleosomes. Because the SAGA complex mediates histone H3 acetylation, we sought to determine to what extent the Gcn5 bromodomain directly modulates histone acetylation activity. Kinetic analysis of SAGA-mediated acetylation of nucleosomal substrates reveals that this bromodomain: 1) is required for the cooperative acetylation of nucleosomes, 2) enhances acetylation of an H3 histone tail when the other H3 tail within a nucleosome is already acetylated, and 3) augments the acetylation turnover of nucleosomes previously acetylated at lysine 16 of the histone H4 tails. These results indicate that the Gcn5 bromodomain promotes the establishment of nucleosome acetylation through multiple mechanisms and more generally show how chromatin recognition domains can modulate the enzymatic activity of chromatin modifying complexes.

Abstract
Histones are subject to numerous post-translational modifications that correlate with the state of higher-order chromatin structure and gene expression. However, it is not clear whether changes in these epigenetic marks are causative regulatory factors in chromatin structure changes or whether they play a mainly reinforcing or maintenance role. In Drosophila phosphorylation of histone H3S10 in euchromatic chromatin regions by the JIL-1 tandem kinase has been implicated in counteracting heterochromatization and gene silencing. Here we show, using a LacI-tethering system, that JIL-1 mediated ectopic histone H3S10 phosphorylation is sufficient to induce a change in higher-order chromatin structure from a condensed heterochromatin-like state to a more open euchromatic state. This effect was absent when a ;kinase dead' LacI-JIL-1 construct without histone H3S10 phosphorylation activity was expressed. Instead, the 'kinase dead' construct had a dominant-negative effect, leading to a disruption of chromatin structure that was associated with a global repression of histone H3S10 phosphorylation levels. These findings provide direct evidence that the epigenetic histone tail modification of H3S10 phosphorylation at interphase can function as a causative regulator of higher-order chromatin structure in Drosophila in vivo.

Abstract
Histone modifications and variants have key roles in the activation and silencing of genes. Phosphorylation of histone H3 at serine 10 and serine 28 is involved in transcriptional activation of genes responding to stress or mitogen-stimulated signaling pathways. The distribution of H3-modified isoforms in G0 phase chicken erythrocyte chromatin was investigated. H3 phosphorylated at serine 28 was found highly enriched in the active/competent gene fractions, as was H3 di- and trimethylated at lysine 4. The H3 variant H3.3 in this chromatin fraction was preferentially phosphorylated at serine 28. Conversely, H3 phosphorylated at serine 10 was present in all chromatin fractions, while H3 dimethylated at lysine 9 was associated with the chromatin-containing repressed genes. H3 phosphorylated at serine 28 was located at the promoter region of the transcriptionally active, but not competent, histone H5 and β-globin genes. We provide evidence that H3.3 phosphorylated at serine 28 was present in labile nucleosomes. We propose that destabilized nucleosomes containing H3.3 phosphorylated at serine 28 aid in the dynamic disassembly–assembly of nucleosomes in active promoters.

Abstract
Histones are the main protein components of chromatin: they undergo extensive post-translational modifications, particularly acetylation, methylation, phosphorylation, ubiquitination and ADP-ribosylation which modify the structural/functional properties of chromatin. Post-translational modifications of the N-terminal tails of the core histones within the nucleosome particle are thought to act as signals from the chromatin to the cell, for various processes. Thus, in many ways histone tails can be viewed as complex protein-protein interaction surfaces that are regulated by numerous post-translational modifications. Histone phosphorylation has been linked to chromosome condensation/segregation, activation of transcription, apoptosis and DNA damage repair. In plants, the cell cycle dependent phosphorylation of histone H3 has been described; it is hyperphosphorylated at serines 10/28 and at threonines 3/11 during both mitosis and meiosis in patterns that are specifically coordinated in both space and time. Although this post-translational modification is highly conserved, data show that the chromosomal distribution of individual modifications can differ between groups of eukaryotes. Initial results indicate that members of the plant Aurora kinase family have the capacity to control cell cycle regulated histone H3 phosphorylation, and in addition we describe other potential H3 kinases and discuss their functions.

Abstract
The epigenetic phospho-serine 10 modification of histone H3 has been a puzzle due to its association with two apparently opposed chromatin states. It is found at elevated levels on the highly condensed, transcriptionally inactive mitotic chromosomes yet is also correlated with the more extended chromatin configuration of active genes, euchromatic interband regions, and activated heat shock puffs of Drosophila polytene chromosomes. In addition, phosphorylation of histone H3S10 is up-regulated on the hypertranscribed male X chromosome. Here we review the cellular effects of histone H3S10 phosphorylation and discuss a model for its involvement in regulating chromatin organization and heterochromatization that would be applicable to both interphase and mitotic chromosomes.

Abstract
The acetylation of histone H4 on lysine 16 is a crucial event in switching chromatin from a repressive to a transcriptionally active state. Acetylation at histone H4 lysine 16 is involved in many cellular processes in organisms as diverse as yeast and humans. A recent biochemical study pinpoints this particular acetylation mark as a switch for changing chromatin from a repressive to a transcriptionally active state.

Abstract
Acetylation of histone H4 on lysine 16 (H4-K16Ac) is a prevalent and reversible posttranslational chromatin modification in eukaryotes. To characterize the structural and functional role of this mark, we used a native chemical ligation strategy to generate histone H4 that was homogeneously acetylated at K16. The incorporation of this modified histone into nucleosomal arrays inhibits the formation of compact 30-nanometer-like fibers and impedes the ability of chromatin to form cross-fiber interactions. H4-K16Ac also inhibits the ability of the adenosine triphosphate-utilizing chromatin assembly and remodeling enzyme ACF to mobilize a mononucleosome, indicating that this single histone modification modulates both higher order chromatin structure and functional interactions between a nonhistone protein and the chromatin fiber.

Abstract
There has been remarkable progress in the last 20 years in defining the molecular mechanisms that regulate initiation of DNA synthesis in eukaryotic cells. Replication origins in the DNA nucleate the ordered assembly of protein factors to form a prereplication complex (preRC) that is poised for DNA synthesis. Transition of the preRC to an active initiation complex is regulated by cyclin-dependent kinases and other signaling molecules, which promote further protein assembly and activate the mini chromosome maintenance helicase. 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 information with associated epigenetic modifications. Thus, we will begin by describing chromatin structure, and how the cell generally controls access to the DNA. Access to the DNA requires active chromatin remodeling, specific histone modifications, and regulated histone deposition. Studies in transcription have revealed a variety of mechanisms that regulate DNA access, and some of these are likely to be shared with DNA replication. We will briefly describe heterochromatin as a model for an epigenetically inherited chromatin state. Next, we will describe the mechanisms of replication initiation and how these are affected by constraints of chromatin. Finally, chromatin must be reassembled with appropriate modifications following passage of the replication fork, and our third major topic will be the reassembly of chromatin and its associated epigenetic marks. Thus, in this chapter, we seek to bring together the studies of replication initiation and the studies of chromatin into a single holistic narrative.
