    Laminin signals initiate the reciprocal loop that informs breast-specific gene expression and homeostasis by activating NO, p53 and microRNAs

    Saori Furuta, Gang Ren ... Mina J Bissell
    Endogenous laminins are necessary to build a functional acinus via generating NO, activating p53, HOXD10 and other positive players, but tumor cells neither make laminin nor generate NO, unless they are reverted to an organized structure.

    SIRT2 deacetylase regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation

    Mohsen Sarikhani, Sneha Mishra ... Nagalingam R Sundaresan
    Mass spectroscopy, molecular modeling and/or molecular dynamics simulations reveal how acetylation regulates the activity of GSK3 isoforms independent of inhibitory phosphorylation.

    TANGO1 builds a machine for collagen export by recruiting and spatially organizing COPII, tethers and membranes

    Ishier Raote, Maria Ortega-Bellido ... Vivek Malhotra
    TANGO1 creates a sub-compartment at the endoplasmic reticulum, to segregate and export fully assembled bulky cargoes.

    Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria

    FoSheng Hsu, Stephanie Spannl ... Marino Zerial
    Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.

    Proteolytic processing of palmitoylated Hedgehog peptides specifies the 3-4 intervein region of the Drosophila wing

    Sabine Schürmann, Georg Steffes ... Kay Grobe
    Proteolysis of lipidated N-terminal peptides that tether Hedgehog morphogens to the surface of source cells is absolutely required for their coupled release and bioactivation in vivo in Drosophila melanogaster.

    Molecular mechanism to target the endosomal Mon1-Ccz1 GEF complex to the pre-autophagosomal structure

    Jieqiong Gao, Lars Langemeyer ... Christian Ungermann
    The endosomal GEF Mon1-Ccz1 binds to Atg8 on autophagosomes, and recruits its substrate, the Rab7-like Ypt7, which then mediates fusion of the autophagosomes with the lysosome.

    Site-specific glycosylation regulates the form and function of the intermediate filament cytoskeleton

    Heather J Tarbet, Lee Dolat ... Michael Boyce
    The in vivo modification of the canonical intermediate filament protein vimentin with O-linked beta-N-acetylglucosamine affects its function in filament assembly, cell migration and host-pathogen interactions.

    Intermediate Filaments: The sweet side of vimentin

    Natasha T Snider, Nam-On Ku, M Bishr Omary
    A protein modification called O-linked glycosylation regulates the interactions between vimentin molecules under normal conditions, and the ability of Chlamydia bacteria to replicate after they infect cells.

    TGF-β uses a novel mode of receptor activation to phosphorylate SMAD1/5 and induce epithelial-to-mesenchymal transition

    Anassuya Ramachandran, Pedro Vizán ... Caroline S Hill
    SMAD1/5 signaling is essential for the full transforming growth factor β (TGF-β)-induced transcriptional program and physiological responses and is induced via a novel receptor activation mechanism, involving two distinct type I receptors.

    Bipolar filaments of human nonmuscle myosin 2-A and 2-B have distinct motile and mechanical properties

    Luca Melli, Neil Billington ... James R Sellers
    Individual nonmuscle myosin 2 filaments in cells may differ their mechanical and kinetic properties depending on the myosin paralog composition giving the cells a mechanism for fine tuning the output of a given nonmuscle myosin filament.
