    miR-142 orchestrates a network of actin cytoskeleton regulators during megakaryopoiesis

    Elik Chapnik, Natalia Rivkin ... Eran Hornstein
    miR-142 is instrumental for actin homeostasis, and its loss disrupts the cytoskeleton organization and thrombopoiesis of megakaryocytes.

    tRNA synthetase counteracts c-Myc to develop functional vasculature

    Yi Shi, Xiaoling Xu ... Xiang-Lei Yang
    In addition to its cytoplasmic role for translation, the seryl-tRNA synthetase also antagonizes the c-Myc transcription factor in the nucleus to transcriptionally repress the growth factor VEGFA and ensure proper development of the vasculature in vertebrates.

    SM proteins Sly1 and Vps33 co-assemble with Sec17 and SNARE complexes to oppose SNARE disassembly by Sec18

    Braden T Lobingier, Daniel P Nickerson ... Alexey J Merz
    Sec1/Munc18 (SM) proteins shield SNARE complexes from NSF/Sec18-mediated disassembly through cooperative binding interactions with SNARE complexes and the universal co-chaperone α-SNAP/Sec17.

    MELK is an oncogenic kinase essential for mitotic progression in basal-like breast cancer cells

    Yubao Wang, Young-Mi Lee ... Jean J Zhao
    Maternal embryonic leucine zipper kinase (MELK) is a new anti-cancer target that is highly selective for basal-like breast cancer.

    SLY1 and Syntaxin 18 specify a distinct pathway for procollagen VII export from the endoplasmic reticulum

    Cristina Nogueira, Patrik Erlmann ... Vivek Malhotra
    A cross-linking screen finds proteins that interact with TANGO1 to export Procollagen VII, and suggests a new model for the secretion of these bulky cargoes that are involved in skin and bone formation.

    Pharmacological inhibition of cystine–glutamate exchange induces endoplasmic reticulum stress and ferroptosis

    Scott J Dixon, Darpan N Patel ... Brent R Stockwell
    Erastin and sorafenib inhibit system xc- and induce ER stress, suggesting these may be useful tools for probing the functions of system xc- and its role in inducing ER stress and ferroptosis.

    Reconstitution of dynein transport to the microtubule plus end by kinesin

    Anthony J Roberts, Brian S Goodman, Samara L Reck-Peterson
    In vitro reconstitution reveals how a system of molecules works together to transport the motor protein dynein to the start of its track.

    Mechanisms of organelle biogenesis govern stochastic fluctuations in organelle abundance

    Shankar Mukherji, Erin K O'Shea
    A systematic comparison of experimentally measured and theoretically predicted magnitudes of organelle abundance fluctuations suggests that budding yeast produces the maximum level of variability in organelle abundance that can be generated by organelle biogenesis pathways.

    MUL1 acts in parallel to the PINK1/parkin pathway in regulating mitofusin and compensates for loss of PINK1/parkin

    Jina Yun, Rajat Puri ... Ming Guo
    By reducing mitochondrial fusion, MUL1 compensates for the mutations in PINK1 or parkin that underlie certain cases of Parkinson's disease.
