    Plasmodium Niemann-Pick type C1-related protein is a druggable target required for parasite membrane homeostasis

    Eva S Istvan et al.
    The malaria parasite Niemann-Pick Type C1-related protein is an important new antimalarial target.

    C1 neurons are part of the circuitry that recruits active expiration in response to the activation of peripheral chemoreceptors

    Milene R Malheiros-Lima et al.
    An unbiased description reveals potential implications for understanding the developmental mechanisms that match respiratory supply and demand during hypoxia.

    Genome-wide CRISPRi screening identifies OCIAD1 as a prohibitin client and regulatory determinant of mitochondrial Complex III assembly in human cells

    Maxence Le Vasseur et al.
    OCIAD1 associates with prohibitin assemblies and regulates the proteolytic processing and stability of the catalytical Complex III subunit cytochrome c1.

    Multiple mechanisms link prestimulus neural oscillations to sensory responses

    Luca Iemi et al.
    Neural oscillations prior to a stimulus modulate the strength of early and late responses in opposite directions via distinct mechanisms.

    Structure of the Helicobacter pylori Cag type IV secretion system

    Jeong Min Chung et al.
    The Helicobacter pylori Cag T4SS has unique structural features, including unexpected symmetry mismatch between sub-complexes, with implications for protein secretion.

    Structural basis for transcription complex disruption by the Mfd translocase

    Jin Young Kang et al.
    Seven distinct cryo-electron microscopy structures delineate the elaborate mechanism for how E. coli Mfd, a transcription repair coupling factor, disassembles the RNA polymerase transcription elongation complex to initiate transcription-coupled repair.

    Lysosomal cholesterol export reconstituted from fragments of Niemann-Pick C1

    Michael Nguyen Trinh et al.
    The N-terminal domain of one NPC1 molecule can transfer its cholesterol to another NPC1 molecule lacking the N-terminal domain, suggesting that NPC1 forms multimers that transport cholesterol out of lysosomes.

    The crystal structure of bromide-bound GtACR1 reveals a pre-activated state in the transmembrane anion tunnel

    Hai Li et al.
    Substrate-induced structural changes in GtACR1 provide new insight into the chemical mechanism of natural light-gated anion conductance and facilitate its optimization for photoinhibition of neuron firing in optogenetics.

    Major genetic discontinuity and novel toxigenic species in Clostridioides difficile taxonomy

    Daniel R Knight et al.
    The Clostridioides difficile taxonomy is characterised by major taxonomic incoherence and clear species boundaries.

    CYK-4 functions independently of its centralspindlin partner ZEN-4 to cellularize oocytes in germline syncytia

    Kian-Yong Lee et al.
    The CYK-4 subunit of the broadly conserved intercellular bridge component centralspindlin, but not its ZEN-4 subunit, is essential for the cytokinesis-like closure of intercellular bridges that cellularizes oocytes to separate them from germline syncytia.
