    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.

    The conformation of the histone H3 tail inhibits association of the BPTF PHD finger with the nucleosome

    Emma A Morrison, Samuel Bowerman ... Catherine A Musselman
    The BPTF PHD finger is inhibited from binding the methylated H3 tails in the context of the nucleosome due to their robust interaction with the nucleosomal DNA, which can be modulated by additional histone PTMs.

    Rev7 and 53BP1/Crb2 prevent RecQ helicase-dependent hyper-resection of DNA double-strand breaks

    Bryan A Leland, Angela C Chen ... Megan C King
    A single-cell assay reveals that the genetic rewiring that underlies PARP inhibitor resistance drives altered DNA double-strand break end resection pathway choice.

    Human LINE-1 retrotransposition requires a metastable coiled coil and a positively charged N-terminus in L1ORF1p

    Elena Khazina, Oliver Weichenrieder
    Human LINE-1 retrotransposition is found to critically depend on the rapidly evolving N-terminal sequence of the LINE-1 ORF1 protein and on the metastability of its coiled coil domain, indicating uncharacterized steps in LINE-1 retrotransposition.

    Distinct roles of ATM and ATR in the regulation of ARP8 phosphorylation to prevent chromosome translocations

    Jiying Sun, Lin Shi ... Satoshi Tashiro
    ATM plays an important role in maintaining the fidelity of DNA repair through the regulation of ARP8 phosphorylation to prevent the chromosome abnormality.

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

    Hani Ebrahimi, Hirohisa Masuda ... Julia Promisel Cooper
    The nuclear periphery houses compositionally and functionally distinct domains, one of which provides a 'safe zone' for replication and reassembly of heterochromatic genome regions.

    Stochastic tuning of gene expression enables cellular adaptation in the absence of pre-existing regulatory circuitry

    Lydia Freddolino, Jamie Yang ... Saeed Tavazoie
    Stochastic tuning of gene expression could be a common mechanism through which eukaryotic cells adapt to challenging external environments, potentially including survival of infectious organisms within the host and adaptation of cancer cells to chemotherapy.

    A compartmentalized signaling network mediates crossover control in meiosis

    Liangyu Zhang, Simone Köhler ... Abby F Dernburg
    A regulatory circuit that localizes to the synaptonemal complex, a liquid crystalline compartment between chromosomes, ensures crossing-over while limiting the number of crossovers between homologous chromosomes during meiosis.

    A genetic program mediates cold-warming response and promotes stress-induced phenoptosis in C. elegans

    Wei Jiang, Yuehua Wei ... Dengke K Ma
    A gene regulatory program regulating thermal stress response and organismic death.

    Modulation of Prdm9-controlled meiotic chromosome asynapsis overrides hybrid sterility in mice

    Sona Gregorova, Vaclav Gergelits ... Jiri Forejt
    Prdm9-generated meiotic asynapsis of homologous chromosomes in mouse subspecific hybrids causes hybrid sterility and can be reversed by introducing random stretches of consubspecific sequence (≥ 27Mb) on four chromosomes most sensitive to asynapsis.
