    Quantifying absolute gene expression profiles reveals distinct regulation of central carbon metabolism genes in yeast

    Rosemary Yu, Egor Vorontsov ... Jens Nielsen
    Global gene expression control mechanisms are modeled using a large dataset consisting of absolute-quantitative proteomics, transcriptomics, and partial metabolomics of Saccharomyces cerevisiae at a wide range of growth conditions.

    Systematic functional analysis of rab GTPases reveals limits of neuronal robustness to environmental challenges in flies

    Friederike E Kohrs, Ilsa-Maria Daumann ... P Robin Hiesinger
    The first complete null mutant collection of all rab GTPase genes in a multicellular organism uncovers neuronal development and function sensitive to environmental challenges in Drosophila.

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

    Agnieszka Fatalska, Emma Stepinac ... David M Glover
    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, Andreas Prestel ... Stine Falsig Pedersen
    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.

    Pre-complexation of talin and vinculin without tension is required for efficient nascent adhesion maturation

    Sangyoon J Han, Evgenia V Azarova ... Gaudenz Danuser
    Pre-complexation of vinculin with talin’s R8 domain facilitates nascent adhesion maturation by unfolding talin, increasing vinculin binding, and thereby transmitting traction forces to the environment.

    The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

    Margaret E Torrence, Michael R MacArthur ... Brendan D Manning
    ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

    A nuclear-based quality control pathway for non-imported mitochondrial proteins

    Viplendra PS Shakya, William A Barbeau ... Adam L Hughes
    During times of mitochondrial impairment, non-imported mitochondrial precursor proteins are targeted to the nucleus for proteasome-dependent degradation.

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

    Dominik Schumacher, Andrea Harms ... Lotte Søgaard-Andersen
    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.

    eIF2B conformation and assembly state regulate the integrated stress response

    Michael Schoof, Morgane Boone ... Peter Walter
    eIF2-P activates the integrated stress response by inducing a conformational change in eIF2B that decreases substrate (eIF2) binding and reduces eIF2B's catalytic activity.
