    Frequency-selective control of cortical and subcortical networks by central thalamus

    Jia Liu et al.
    Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.

    Crystal structures of virus-like photosystem I complexes from the mesophilic cyanobacterium Synechocystis PCC 6803

    Yuval Mazor et al.
    The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

    TANGO1 recruits ERGIC membranes to the endoplasmic reticulum for procollagen export

    António JM Santos et al.
    Building on previous work (Nogueira et al., 2014), we describe a mechanism for the generation of a mega-carrier for the export of bulky procollagen from the endoplasmic reticulum.

    A putative ATPase mediates RNA transcription and capping in a dsRNA virus

    Xuekui Yu et al.
    Atomic structures suggest a novel mechanism for the regulation of mRNA transcription and capping in dsRNA viruses.

    Pharmacological dimerization and activation of the exchange factor eIF2B antagonizes the integrated stress response

    Carmela Sidrauski et al.
    A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

    Dopamine receptor 1 neurons in the dorsal striatum regulate food anticipatory circadian activity rhythms in mice

    Christian M Gallardo et al.
    For mice, knowing when it is time to feed is dependent on the neurotransmitter dopamine and the D1R receptor of neurons in the dorsal striatum.

    New tools for automated high-resolution cryo-EM structure determination in RELION-3

    Jasenko Zivanov et al.
    RELION-3 calculates single-particle reconstructions to higher resolution and with less user-interactions than previously available versions.

    Planar cell polarity signaling coordinates oriented cell division and cell rearrangement in clonally expanding growth plate cartilage

    Yuwei Li et al.
    Through the interaction between PCP signaling and N-cadherin, oriented cell division and cell rearrangement are coordinated to establish the appropriate tissue architecture critical for limb skeletal morphogenesis.

    Distinct RanBP1 nuclear export and cargo dissociation mechanisms between fungi and animals

    Yuling Li et al.
    Animal RanBP1 nuclear export and cargo dissociation mechanisms are surprisingly different from yeast, due to mutations of critical residues, leading to greater nuclear transport efficiency and higher energy cost.

    Mechanism of B-box 2 domain-mediated higher-order assembly of the retroviral restriction factor TRIM5α

    Jonathan M Wagner et al.
    Higher-order assembly enables and links pathogen recognition and downstream steps in the TRIM5-mediated anti-HIV response.
