    Three-dimensional reconstruction of a whole insect reveals its phloem sap-sucking mechanism at nano-resolution

    Xin-Qiu Wang et al.
    3D reconstruction for an insect provides new internal structures at nanometer resolution, and the reconstructed feeding insect reveals unexpected contraction of stylet protractors and suggested a novel phloem sap-sucking model.

    Synaptotagmin-7 places dense-core vesicles at the cell membrane to promote Munc13-2- and Ca2+-dependent priming

    Bassam Tawfik et al.
    Synaptotagmin-7 acts synergistically with synaptotagmin-1 by placing vesicles close to the plasma membrane within reach of the SNARE/Munc13-complex, supporting their priming and setting the stage for fast and slow fusion.

    The dimeric Golgi protein Gorab binds to Sas6 as a monomer to mediate centriole duplication

    Agnieszka Fatalska et al.
    The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.

    Dynamic Na+/H+ exchanger 1 (NHE1) – calmodulin complexes of varying stoichiometry and structure regulate Ca2+-dependent NHE1 activation

    Lise M Sjøgaard-Frich et al.
    NHE1-CaM complexes of multiple stoichiometries regulate cellular Ca2+-dependent NHE1 activity and can contribute to NHE1 dimerization, the latter shown by the NMR structure of CaM linking two NHE1 cytosolic tails.

    Promoter-specific changes in initiation, elongation, and homeostasis of histone H3 acetylation during CBP/p300 inhibition

    Emily Hsu et al.
    CBP/p300 acetylation of histone H3 at promoters and enhancers stimulates transcriptional elongation through recruitment of the super-elongation complex and BRD4.

    FRET-based dynamic structural biology: Challenges, perspectives and an appeal for open-science practices

    Eitan Lerner et al.
    A summary of the current “state-of-the-field” of single-molecule FRET used for probing biomolecular structural dynamics.

    A gradient of Wnt activity positions the neurosensory domains of the inner ear

    Magdalena Żak, Nicolas Daudet
    Manipulations of Wnt signalling in the chicken embryo reveal how it controls in a dose-dependent manner the formation of the neurosensory territories of the early developing inner ear.

    Human ORC/MCM density is low in active genes and correlates with replication time but does not delimit initiation zones

    Nina Kirstein et al.
    Replication origins are established throughout the genome with the exception of transcribed genes, and the local chromatin composition likely modulates the density of ORC and MCM as well as origin activation.

    PomX, a ParA/MinD ATPase activating protein, is a triple regulator of cell division in Myxococcus xanthus

    Dominik Schumacher et al.
    In the PomX/Y/Z cell division regulatory system, PomX is a PomZ ATPase activating protein, a scaffold for PomX/Y/Z complex formation, and important for fission of the PomX/Y/Z complex during division.

    SABRE populates ER domains essential for cell plate maturation and cell expansion influencing cell and tissue patterning

    Xiaohang Cheng, Magdalena Bezanilla
    SABRE, which is present in a wide range of eukaryotes, localizes to ER subdomains in plants, impacting cell expansion and callose deposition during cell plate maturation.
