    The modular mechanism of chromocenter formation in Drosophila

    Madhav Jagannathan et al.
    Cell biological study reveals the mechanism by which multiple satellite-DNA-binding proteins cooperate to form chromocenter to encapsulate the full complement of chromosomes.

    Chromocenters: Bundling up DNA

    Susan A Gerbi
    Structures known as chromocenters, comprising satellite DNA and proteins such as D1 or HMGA1, help to contain DNA inside the nucleus between cell divisions.

    A conserved function for pericentromeric satellite DNA

    Madhav Jagannathan et al.
    Satellite DNA mediates clustering of multiple chromosomes via formation of chromocenter to encapsulate the full complement of the genome into a single nucleus.

    The MBD7 complex promotes expression of methylated transgenes without significantly altering their methylation status

    Dongming Li et al.
    The METHYL-CpG-BINDING DOMAIN 7 (MBD7) complex promotes the activation (rather than repression) of transgenes that undergo DNA methylation and it does so without significantly altering their methylation status, placing this complex downstream of DNA methylation.

    The cell proliferation antigen Ki-67 organises heterochromatin

    Michal Sobecki et al.
    Antigen Ki-67, which is widely used as a cell proliferation marker, controls heterochromatin organisation and gene expression.

    The transcription factor Hey and nuclear lamins specify and maintain cell identity

    Naama Flint Brodsly et al.
    Hey together with LaminC continuously supervise nuclear organisation and differentiated enterocyte identity, a regulation that is lost upon ageing, resulting in loss of gut homeostasis.

    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.

    Rif1 inhibits replication fork progression and controls DNA copy number in Drosophila

    Alexander Munden et al.
    To regulate DNA copy number during development in Drosophila, the SUUR protein recruits Rif1 to replisomes where Rif1 inhibits replication fork progression, thus controlling copy number independently of origin firing.

    Bicoid gradient formation and function in the Drosophila pre-syncytial blastoderm

    Zehra Ali-Murthy, Thomas B Kornberg
    The concentration gradient of Bicoid protein positions gene expression domains along the anterior/posterior axis of the Drosophila embryo during the cleavage, pre-syncytial blastoderm stages.

    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.
