    The E3 ubiquitin ligase ZNRF2 is a substrate of mTORC1 and regulates its activation by amino acids

    Gerta Hoxhaj, Edward Caddye ... Carol MacKintosh
    The ZNRF2 enzyme helps the mTOR protein complex to sense amino acid levels and regulate mammalian cell growth.

    The structure of the core NuRD repression complex provides insights into its interaction with chromatin

    Christopher J Millard, Niranjan Varma ... John WR Schwabe
    An extensive interface between the proteins RBBP4 and MTA1 defines the three-dimensional architecture of the core NuRD complex and determines the recruitment of the complex to chromatin.

    A SPOPL/Cullin-3 ubiquitin ligase complex regulates endocytic trafficking by targeting EPS15 at endosomes

    Michaela Gschweitl, Anna Ulbricht ... Matthias Peter
    The poorly characterized BTB-protein SPOPL is required to maintain the function of the late endosomal system and the endocytic adaptor EPS15 is therein targeted by the SPOPL/Cullin-3 ubiquitin ligase complex for degradation.

    SOX2 O-GlcNAcylation alters its protein-protein interactions and genomic occupancy to modulate gene expression in pluripotent cells

    Samuel A Myers, Sailaja Peddada ... Barbara Panning
    A post-translational modification called O-GlcNAcylation modulates the activity of the SOX2 transcription factor in pluripotent stem cells.

    Time-resolved multimodal analysis of Src Homology 2 (SH2) domain binding in signaling by receptor tyrosine kinases

    Joshua A Jadwin, Dongmyung Oh ... Bruce J Mayer
    The recruitment of SH2-containing proteins to Epidermal Growth Factor in cells happens more slowly than predicted by in vitro techniques.

    VEGFR-2 conformational switch in response to ligand binding

    Sarvenaz Sarabipour, Kurt Ballmer-Hofer, Kalina Hristova
    A receptor for vascular endothelial growth factor forms dimers in the absence of its ligand, and ligand-binding leads to structural changes that result in increased kinase phosphorylation.

    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz, Jens Bassler, Joachim E Schultz
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    Acquisition of exogenous haem is essential for tick reproduction

    Jan Perner, Roman Sobotka ... Petr Kopacek
    The lack of haem biosynthetic and degradative pathways in ticks offers new strategies to combat these parasites.

    Ataxin-1 oligomers induce local spread of pathology and decreasing them by passive immunization slows Spinocerebellar ataxia type 1 phenotypes

    Cristian A Lasagna-Reeves, Maxime WC Rousseaux ... Huda Y Zoghbi
    Building on previous work (Lasagna-Reeves et al., 2015) it is shown that polyglutamine ATXN1 oligomers propagate locally in SCA1 mice, and that passive immunotherapy targeting soluble oligomers can lead to an improvement in motor coordination and a modest increase in life span.

    A glucose-starvation response regulates the diffusion of macromolecules

    Ryan P Joyner, Jeffrey H Tang ... Karsten Weis
    During stress conditions, eukaryotic cells dramatically alter their biophysical properties to regulate diffusion of macromolecules.
