    Tripartite suppression of fission yeast TORC1 signaling by the GATOR1-Sea3 complex, the TSC complex, and Gcn2 kinase

    Tomoyuki Fukuda, Fajar Sofyantoro ... Kazuhiro Shiozaki
    Sea3, a presumed subunit of the GATOR2 complex in fission yeast, is required for the GATOR1 function that attenuates TORC1 in parallel with the TSC complex and Gcn2 kinase.

    The GATOR complex regulates an essential response to meiotic double-stranded breaks in Drosophila

    Youheng Wei, Lucia Bettedi ... Mary A Lilly
    The GATOR complex regulates TORC1 activity during meiosis.

    Ragulator and GATOR1 complexes promote fission yeast growth by attenuating TOR complex 1 through Rag GTPases

    Kim Hou Chia, Tomoyuki Fukuda ... Kazuhiro Shiozaki
    The Rag-family GTPases, known activators of TOR complex 1 (TORC1), also function as attenuator that prevents deregulated hyperactivation of TORC1 signaling.

    Robust perisomatic GABAergic self-innervation inhibits basket cells in the human and mouse supragranular neocortex

    Viktor Szegedi, Melinda Paizs ... Karri Lamsa
    Abundant self-inhibitory synapses in the layer 2/3 of human neocortex strongly regulate the function of basket cells.

    Activation of GCN2 kinase by ribosome stalling links translation elongation with translation initiation

    Ryuta Ishimura, Gabor Nagy ... Susan L Ackerman
    Activation of the integrated stress response by stalled translation elongation complexes attenuates neurodegeneration, and demonstrates a protective link between a decrease in the rate of translation initiation and defects in translation elongation.

    Binding to nucleosome poises human SIRT6 for histone H3 deacetylation

    Ekaterina Smirnova, Emmanuelle Bignon ... Adam Ben Shem
    The dynamics of Sirtuin 6 binding to the nucleosome shed light on how it is able to deacetylate histone H3 lysines close to the core, including K27.
    1. Neuroscience

    Parallel processing of quickly and slowly mobilized reserve vesicles in hippocampal synapses

    Juan Jose Rodriguez Gotor, Kashif Mahfooz ... John F Wesseling
    Reevaluation of reserve synaptic vesicle pools supports a new model of presynaptic function.

    Mutation in ATG5 reduces autophagy and leads to ataxia with developmental delay

    Myungjin Kim, Erin Sandford ... Margit Burmeister
    A genetic mutation that impairs autophagic flux leads to neurodegeneration and can cause ataxia and developmental delay in children.

    Dynamics of mTORC1 activation in response to amino acids

    Maria Manifava, Matthew Smith ... Nicholas T Ktistakis
    Activation by amino acids causes mTORC1 to translocate transiently to the lysosomal surface.

    Digital wearable insole-based identification of knee arthropathies and gait signatures using machine learning

    Matthew F Wipperman, Allen Z Lin ... Olivier Harari
    Biosensor data collected by digital insoles is comparable to lab-based clinical assessments and can be used to identify subject-specific gait patterns.
