    Impact of nucleic acid and methylated H3K9 binding activities of Suv39h1 on its heterochromatin assembly

    Atsuko Shirai et al.
    Suv39h1 chromodomain possesses nucleic acid-binding activity and this activity is coupled with its H3K9 methylation recognition in assembling heterochromatin.

    The composition and organization of Drosophila heterochromatin are heterogeneous and dynamic

    Joel M Swenson et al.
    Identification of novel components and regulators of heterochromatin reveals a spatially complex and dynamic organization.

    Noncoding RNA-nucleated heterochromatin spreading is intrinsically labile and requires accessory elements for epigenetic stability

    R A Greenstein et al.
    Heterochromatin spreading in fission yeast predominantly produces intergenerationally unstable outcomes, requiring an accessory element that represses histone turnover.

    A histone H3K9M mutation traps histone methyltransferase Clr4 to prevent heterochromatin spreading

    Chun-Min Shan et al.
    A lysine-to-methionine mutation in histone H3 dominantly blocks histone H3K9 methylation by trapping its methyltransferase.

    Ovaries absent links dLsd1 to HP1a for local H3K4 demethylation required for heterochromatic gene silencing

    Fu Yang et al.
    A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..

    Natural depletion of histone H1 in sex cells causes DNA demethylation, heterochromatin decondensation and transposon activation

    Shengbo He et al.
    Transposon activation during male gametogenesis is caused by interactions between DNA demethylation and linker histone H1, developmental depletion of which promotes pollen fertility.

    Heterochromatin assembly and transcriptome repression by Set1 in coordination with a class II histone deacetylase

    David R Lorenz et al.
    Set1 has roles in chromatin organization and transcriptome control that are largely independent of histone H3 lysine 4 methylation.

    Distinct ‘safe zones’ at the nuclear envelope ensure robust replication of heterochromatic chromosome regions

    Hani Ebrahimi et al.
    The nuclear periphery houses compositionally and functionally distinct domains, one of which provides a 'safe zone' for replication and reassembly of heterochromatic genome regions.

    Heritable capture of heterochromatin dynamics in Saccharomyces cerevisiae

    Anne E Dodson, Jasper Rine
    Single-cell and single-molecule analyses of transient gene expression revealed hitherto unrecognized dynamics in heterochromatin function and defined novel roles for a heterochromatin establishment factor and an understudied sirtuin.

    Methylation of histone H3K23 blocks DNA damage in pericentric heterochromatin during meiosis

    Romeo Papazyan et al.
    A previously unappreciated histone methylation pathway helps limit DNA double-strand break formation and recombination in heterochromatin during meiosis.
