Not yet tested in other applications Scientific Description: Protein post-translational Modification (PTM) is an important reversible event controlling protein activity. The amino-terminal tails of core histones undergo multiple modifications in multiple sites, termed as “histone code” or “epigenetic code”. Arginine methylation in core histones is a major determinant for the formation of active and inactive regions of the genome and therefore plays vital roles in multiple cellular events. In most species, arginine methylation occurs primarily on histones H3 (Arg2, 8, 17, 26) and H4 (Arg2) and has been implicated in both transcriptional activation and silencing. Arginine methylation in histones is carried out by the arginine N-methyltransferase (PRMT), which catalyzes the transfer of a methyl group from S- adenosylmethionine (AdoMet) to a guanidine nitrogen of arginine. Arginine methylation in histones is impaired in the pathologies of cancer and other diseases and therefore, enzymes regulating histone arginine methylation have become promising targets for anti-cancer drugs.

  • Four Enzymes Cooperate to Displace Histone H1 During the First Minute of Hormonal Gene Activation
    Downloaded from genesdev.cshlp.org on September 26, 2021 - Published by Cold Spring Harbor Laboratory Press Four enzymes cooperate to displace histone H1 during the first minute of hormonal gene activation Guillermo Pablo Vicent,1,2 A. Silvina Nacht,1 Jofre Font-Mateu, Giancarlo Castellano, Laura Gaveglia, Cecilia Ballare´, and Miguel Beato Centre de Regulacio´ Geno` mica (CRG), Universitat Pompeu Fabra (UPF), E-08003 Barcelona, Spain Gene regulation by external signals requires access of transcription factors to DNA sequences of target genes, which is limited by the compaction of DNA in chromatin. Although we have gained insight into how core histones and their modifications influence this process, the role of linker histones remains unclear. Here we show that, within the first minute of progesterone action, a complex cooperation between different enzymes acting on chromatin mediates histone H1 displacement as a requisite for gene induction and cell proliferation. First, activated progesterone receptor (PR) recruits the chromatin remodeling complexes NURF and ASCOM (ASC-2 [activating signal cointegrator-2] complex) to hormone target genes. The trimethylation of histone H3 at Lys 4 by the MLL2/MLL3 subunits of ASCOM, enhanced by the hormone-induced displacement of the H3K4 demethylase KDM5B, stabilizes NURF binding. NURF facilitates the PR-mediated recruitment of Cdk2/CyclinA, which is required for histone H1 displacement. Cooperation of ATP-dependent remodeling, histone methylation, and kinase activation, followed by H1 displacement, is a prerequisite for the subsequent displacement of histone H2A/H2B catalyzed by PCAF and BAF. Chromatin immunoprecipitation (ChIP) and sequencing (ChIP-seq) and expression arrays show that H1 displacement is required for hormone induction of most hormone target genes, some of which are involved in cell proliferation.

SUBCLONING, EXPRESSION, AND ENZYMATIC STUDY OF PRMT5 by RAN GUO Under the Direction of Yujun George Zheng ABSTRACT Protein arginine methyltransferases (PRMTs) mediate the transfer of methyl groups to arginine residues in histone and non-histone proteins. PRMT5 is an important member of PRMTs which symmetrically dimethylates arginine 8 in histone H3 (H3R8) and arginine 3 in histone H4 (H4R3). PRMT5 was reported to inhibit some tumor suppressors in leukemia and lymphoma cells and regulate p53 gene, through affecting the promoter of p53. Through methylation of H4R3, PRMT5 can recruit DNA-methyltransferase 3A (DNMT3A) which regulates gene transcription. All the above suggest that PRMT5 has an important function of suppressing cell apoptosis and is a potential anticancer target. Currently, the enzymatic activities of PRMT5 are not clearly understood. In our study, we improved the protein expression methodology and greatly enhanced the yield and quality of the recombinant PRMT5.

Running title: histone modification and gene expression network Keywords: histone modification, gene expression, Bayesian network, causal relationship, epigenetics 1 Downloaded from genome.cshlp.org on September 28, 2021 - Published by Cold Spring Harbor Laboratory Press Abstract Histone modifications are major epigenetic factors regulating gene expression. They play important roles in maintaining stem cell pluripotency and in cancer pathogenesis. Different modifications may combine to form complex ‘histone codes’. Recent high throughput technologies, such as ‘ChIP-chip’ and ‘ChIP-seq’, have generated high resolution maps for many histone modifications on the human genome. Here we use these maps to build a Bayesian network to infer causal and combinatorial relationships among histone modifications and gene expression. A pilot network derived by the same method among polycomb group (PcG) genes and H3K27 trimethylation is accurately supported by current literature. Our unbiased network model among histone modifications is also well supported by cross validation results. It not only confirmed already known relationships, such as those of H3K27me3 to gene silencing, H3K4me3 to gene activation, and the effect of bivalent modification of both H3K4me3 and H3K27me3, but also identified many other relationships that may predict new epigenetic interactions important in epigenetic gene regulation.

  • Anti-H3r2me2(Asym) Antibody
    FOR RESEARCH USE ONLY! 01/20 Anti-H3R2me2(asym) Antibody CATALOG NO.: A2025-100 (100 µl) BACKGROUND DESCRIPTION: Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H3 family. Transcripts from this gene lack poly A tails; instead, they contain a palindromic termination element. This gene is located separately from the other H3 genes that are in the histone gene cluster on chromosome 6p22-p21.3. H3.4; H3/g; H3FT; H3t; HIST3H3; Histone H3; HIST1H3A ALTERNATE NAMES: ANTIBODY TYPE: Polyclonal HOST/ISOTYPE: Rabbit / IgG IMMUNOGEN: A synthetic methylated peptide targeting residues around Arginine 2 of human Histone H3 MOLECULAR WEIGHT: 17 kDa PURIFICATION: Affinity purified FORM: Liquid FORMULATION: In PBS with 0.02% sodium azide, 50% glycerol, pH 7.3 SPECIES REACTIVITY: Human, Mouse, Rat STORAGE CONDITIONS: Store at -20ºC.

  • Reversible Histone Glycation Is Associated with Disease-Related Changes in Chromatin Architecture
    ARTICLE https://doi.org/10.1038/s41467-019-09192-z OPEN Reversible histone glycation is associated with disease-related changes in chromatin architecture Qingfei Zheng 1, Nathaniel D. Omans1,2, Rachel Leicher3,4, Adewola Osunsade 1,4, Albert S. Agustinus 1, Efrat Finkin-Groner1, Hannah D’Ambrosio1, Bo Liu5, Sarat Chandarlapaty 5, Shixin Liu3 & Yael David1,4,6,7 Cellular proteins continuously undergo non-enzymatic covalent modifications (NECMs) that accumulate under normal physiological conditions and are stimulated by changes in the 1234567890():,; cellular microenvironment. Glycation, the hallmark of diabetes, is a prevalent NECM asso- ciated with an array of pathologies. Histone proteins are particularly susceptible to NECMs due to their long half-lives and nucleophilic disordered tails that undergo extensive regulatory modifications; however, histone NECMs remain poorly understood. Here we perform a detailed analysis of histone glycation in vitro and in vivo and find it has global ramifications on histone enzymatic PTMs, the assembly and stability of nucleosomes, and chromatin archi- tecture. Importantly, we identify a physiologic regulation mechanism, the enzyme DJ-1, which functions as a potent histone deglycase. Finally, we detect intense histone glycation and DJ-1 overexpression in breast cancer tumors. Collectively, our results suggest an additional mechanism for cellular metabolic damage through epigenetic perturbation, with implications in pathogenesis. 1 Chemical Biology Program, Sloan Kettering Institute, Memorial Sloan Kettering Cancer Center, New York, NY 10065, USA. 2 Tri-Institutional Training Program in Computational Biology and Medicine, New York, NY 10065, USA. 3 Laboratory of Nanoscale Biophysics and Biochemistry, Rockefeller University, New York, NY 10065, USA. 4 Tri-institutional PhD Program in Chemical Biology, New York, NY 10065, USA.
