    A Meier-Gorlin syndrome mutation in a conserved C-terminal helix of Orc6 impedes origin recognition complex formation

    Franziska Bleichert et al.
    Electron microscopy uncovers the structure of the origin recognition complex (ORC) in metazoans, and reveals how mutations in the ORC6 subunit lead to Meier-Gorlin syndrome in humans.

    Brahma is essential for Drosophila intestinal stem cell proliferation and regulated by Hippo signaling

    Yunyun Jin et al.
    The Brahma chromatin remodelling complex interacts with the Hippo signalling pathway to regulate the proliferation and differentiation of stem cells in the Drosophila midgut.

    Stochastic homeostasis in human airway epithelium is achieved by neutral competition of basal cell progenitors

    Vitor H Teixeira et al.
    Cell replenishment within the airways is governed by the random division of a population of basal progenitor cells, in a process that is accelerated in smokers.

    A genome-to-genome analysis of associations between human genetic variation, HIV-1 sequence diversity, and viral control

    István Bartha et al.
    An innovative strategy in genome analysis has generated a detailed description of how pathogens mutate when facing human genetic diversity.

    Engineered proteins detect spontaneous DNA breakage in human and bacterial cells

    Chandan Shee et al.
    Fluorescent derivatives of a bacteriophage protein that binds double-stranded ends can trap and label genome-destabilizing double-strand DNA breaks in bacterial and human cells, and illuminate the origins of spontaneous DNA breakage in both.

    Position of UNC-13 in the active zone regulates synaptic vesicle release probability and release kinetics

    Keming Zhou et al.
    The precise position of UNC-13 at the active zone near a synapse depends on the N-terminus of the protein, and the C2A domain in particular, and is essential for accelerating neurotransmitter release.

    The role of Cdc42 and Gic1 in the regulation of septin filament formation and dissociation

    Yashar Sadian et al.
    Imaging with electron microscopy and cryo-electron tomography reveals that competition between Cdc42 and Gic1 for the same subunit within septins controls the formation and breakdown of septin filaments.

    Hdac6 regulates Tip60-p400 function in stem cells

    Poshen B Chen et al.
    A normally cytoplasmic deacetylase, Hdac6, localizes to the nucleus in embryonic stem cells, where it regulates the essential Tip60-p400 chromatin remodeling complex.

    Ribosome profiling reveals pervasive and regulated stop codon readthrough in Drosophila melanogaster

    Joshua G Dunn et al.
    Ribosomes translate through stop codons far more often than previously thought, yielding C-terminally extended proteins in a variety of eukaryotes.

    Rasgrp1 mutation increases naïve T-cell CD44 expression and drives mTOR-dependent accumulation of Helios+ T cells and autoantibodies

    Stephen R Daley et al.
    A single point mutation in a Ras activator leads to aberrant constitutive mTOR signaling in peripheral T cells that consequently accumulate as abnormal T helper cells and stimulate the production of autoantibodies by B cells.
