  • The Role of Histone H2av Variant Replacement and Histone H4 Acetylation in the Establishment of Drosophila Heterochromatin
    The role of histone H2Av variant replacement and histone H4 acetylation in the establishment of Drosophila heterochromatin Jyothishmathi Swaminathan, Ellen M. Baxter, and Victor G. Corces1 Department of Biology, Johns Hopkins University, Baltimore, Maryland 21218, USA Activation and repression of transcription in eukaryotes involve changes in the chromatin fiber that can be accomplished by covalent modification of the histone tails or the replacement of the canonical histones with other variants. Here we show that the histone H2A variant of Drosophila melanogaster, H2Av, localizes to the centromeric heterochromatin, and it is recruited to an ectopic heterochromatin site formed by a transgene array. His2Av behaves genetically as a PcG gene and mutations in His2Av suppress position effect variegation (PEV), suggesting that this histone variant is required for euchromatic silencing and heterochromatin formation. His2Av mutants show reduced acetylation of histone H4 at Lys 12, decreased methylation of histone H3 at Lys 9, and a reduction in HP1 recruitment to the centromeric region. H2Av accumulation or histone H4 Lys 12 acetylation is not affected by mutations in Su(var)3-9 or Su(var)2-5. The results suggest an ordered cascade of events leading to the establishment of heterochromatin and requiring the recruitment of the histone H2Av variant followed by H4 Lys 12 acetylation as necessary steps before H3 Lys 9 methylation and HP1 recruitment can take place.

  • TALE-Light Imaging Reveals Maternally Guided, H3k9me2/3-Independent Emergence of Functional Heterochromatin in Drosophila Embryos
    Downloaded from genesdev.cshlp.org on September 29, 2021 - Published by Cold Spring Harbor Laboratory Press TALE-light imaging reveals maternally guided, H3K9me2/3-independent emergence of functional heterochromatin in Drosophila embryos Kai Yuan and Patrick H. O’Farrell Department of Biochemistry, University of California at San Francisco, San Francisco, California 94158, USA Metazoans start embryogenesis with a relatively naïve genome. The transcriptionally inert, late-replicating het- erochromatic regions, including the constitutive heterochromatin on repetitive sequences near centromeres and telomeres, need to be re-established during development. To explore the events initiating heterochromatin forma- tion and examine their temporal control, sequence specificity, and immediate regulatory consequence, we estab- lished a live imaging approach that enabled visualization of steps in heterochromatin emergence on specific satellite sequences during the mid-blastula transition (MBT) in Drosophila. Unexpectedly, only a subset of satellite se- quences, including the 359-base-pair (bp) repeat sequence, recruited HP1a at the MBT. The recruitment of HP1a to the 359-bp repeat was dependent on HP1a’s chromoshadow domain but not its chromodomain and was guided by maternally provided signals. HP1a recruitment to the 359-bp repeat was required for its programmed shift to later replication, and ectopic recruitment of HP1a was sufficient to delay replication timing of a different repeat. Our results reveal that emergence of constitutive heterochromatin follows a stereotyped developmental program in which different repetitive sequences use distinct interactions and independent pathways to arrive at a heterochro- matic state. This differential emergence of heterochromatin on various repetitive sequences changes their replica- tion order and remodels the DNA replication schedule during embryonic development.

  • Drosophila Ribosomal Proteins Are Associated with Linker Histone H1 and Suppress Gene Transcription
    Downloaded from genesdev.cshlp.org on October 2, 2021 - Published by Cold Spring Harbor Laboratory Press Drosophila ribosomal proteins are associated with linker histone H1 and suppress gene transcription Jian-Quan Ni,1,3 Lu-Ping Liu,1,3 Daniel Hess,1 Jens Rietdorf,1 and Fang-Lin Sun1,2,4 1Friedrich Miescher Institute for Biomedical Research, Basel CH-4058, Switzerland; 2Institute of Epigenetics and Cancer Research, School of Medicine, Tsinghua University, Beijing 100080, China The dynamics and function of ribosomal proteins in the cell nucleus remain enigmatic. Here we provide evidence that specific components of Drosophila melanogaster ribosomes copurify with linker histone H1. Using various experimental approaches, we demonstrate that this association of nuclear ribosomal proteins with histone H1 is specific, and that colocalization occurs on condensed chromatin in vivo. Chromatin immunoprecipitation analysis confirmed that specific ribosomal proteins are associated with chromatin in a histone H1-dependent manner. Overexpression of either histone H1 or ribosomal protein L22 in Drosophila cells resulted in global suppression of the same set of genes, while depletion of H1 and L22 caused up-regulation of tested genes, suggesting that H1 and ribosomal proteins are essential for transcriptional gene repression. Overall, this study provides evidence for a previously undefined link between ribosomal proteins and chromatin, and suggests a role for this association in transcriptional regulation in higher eukaryotes.

Using a versatile curriculum, GEP undergraduates undertake projects to improve draft genomic sequences and/or participate in the annotation of these improved sequences. An additional goal of the annotation curriculum is for students to gain a sophisticated understanding of eukaryotic gene structure. Students do so by carefully mapping the protein-coding regions of putative genes from recently- sequenced Drosophila species.

Here we identify chromatin-associated protein and RNA interactions of HP1a by BioTAP-XL mass spectrometry and sequencing from Drosophila S2 cells, embryos, larvae, and adults. Our results reveal an extensive list of known and novel HP1a-interacting proteins, of which we selected three for validation. A strong novel interactor, dADD1 (Drosophila ADD1) (CG8290), is highly enriched in heterochromatin, harbors an ADD domain similar to human ATRX, displays selective binding to H3K9me2 and H3K9me3, and is a classic genetic suppressor of position-effect variegation. Unexpectedly, a second hit, HIPP1 (HP1 and insulator partner protein-1) (CG3680), is strongly connected to CP190-related complexes localized at putative insulator sequences throughout the genome in addition to its colocalization with HP1a in heterochro- matin.
