    A spontaneous genetically induced epiallele at a retrotransposon shapes host genome function

    Tessa M Bertozzi et al.
    A retrotransposon-derived recombination event in inbred mice gives rise to an epiallele and tissue-specific phenotypes.

    Structure of HIV-1 gp41 with its membrane anchors targeted by neutralizing antibodies

    Christophe Caillat et al.
    The structure of gp41with its membrane anchors highlights the flexible linkage of the transmembrane regions and the fuson peptides, which generates an asymmetric conformation, a potential target of MPER bNAbs.

    Spatiotemporal recruitment of RhoGTPase protein GRAF inhibits actomyosin ring constriction in Drosophila cellularization

    Swati Sharma, Richa Rikhy
    The RhoGTPase domain containing protein GRAF recruits to the cleavage furrow during myosin II assembly to hydrolyze Rho-GTP and restrict actomyosin contractility for regulating the time of onset of constriction during Drosophila cellularization.

    Lipoprotein DolP supports proper folding of BamA in the bacterial outer membrane promoting fitness upon envelope stress

    David Ranava et al.
    The envelope stress factor DolP associates with the outer membrane protein assembly machinery and supports proper folding and functioning of BamA contributing to preserve envelope integrity.

    Inverse regulation of Vibrio cholerae biofilm dispersal by polyamine signals

    Andrew A Bridges, Bonnie L Bassler
    The global pathogen Vibrio cholerae monitors environmental polyamines to garner information about numbers of ‘self’ versus ‘other’ in the vicinity, and in response, to remain or disperse from biofilms.

    GAF is essential for zygotic genome activation and chromatin accessibility in the early Drosophila embryo

    Marissa M Gaskill et al.
    Following fertilization, the pioneering transcription factors GAGA factor (GAF) and Zelda are independently required to reprogram the zygotic genome of Drosophila and activate the first wave of gene expression.

    Glia actively sculpt sensory neurons by controlled phagocytosis to tune animal behavior

    Stephan Raiders et al.
    A peripheral sense-organ glia actively engulfs fragments of a sensory neuron ending to modify neuron shape and associated animal sensory behavior in Caenorhabditis elegans..

    Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

    Taro Maeda et al.
    The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

    Methionine restriction breaks obligatory coupling of cell proliferation and death by an oncogene Src in Drosophila

    Hiroshi Nishida et al.
    Src, an oncogene, promotes both cell proliferation and cell death simultaneously, which can be regulated by dietary methionine.
