    The cryo-EM structure of the human uromodulin filament core reveals a unique assembly mechanism

    Jessica J Stanisich et al.
    Cryo-EM reveals that an unexpected domain separation in the zona pellucida module of uromodulin is required for its assembly to filamentous homopolymers that promote pathogen clearance in urinary tract infections.

    Metabolic network rewiring of propionate flux compensates vitamin B12 deficiency in C. elegans

    Emma Watson et al.
    The roundworm C. elegans transcriptionally activates five genes comprising an alternate propionate breakdown pathway when dietary vitamin B12 is low or when the canonical pathway is compromised.

    Upregulation of neurovascular communication through filamin abrogation promotes ectopic periventricular neurogenesis

    Shauna L Houlihan et al.
    Analyses based on the mouse model of a human genetic disease reveal that the neuron production of cerebral tissue can be boosted by escalated signaling between neural progenitors and the vasculature.

    Targeting a cell surface vitamin D receptor on tumor-associated macrophages in triple-negative breast cancer

    Fernanda I Staquicini et al.
    A peptide motif targeting tumor-infiltrating macrophage in triple-negative breast cancer delays tumor growth and favors an antitumor immune response.

    Cryo-EM structures demonstrate human IMPDH2 filament assembly tunes allosteric regulation

    Matthew C Johnson, Justin M Kollman
    Assembly of the human enzyme inosine monophosphate dehydrogenase 2 into filaments promotes substrate-dependent resistance to feedback inhibition by downstream products, promoting increased flux during proliferative states.

    A vitamin-B2-sensing mechanism that regulates gut protease activity to impact animal’s food behavior and growth

    Bin Qi et al.
    The availability of an essential dietary micronutrient is evaluated by an intestinal signaling system that in turn regulates food-uptake and response behaviors by modulating protease expression.

    Rad52-Rad51 association is essential to protect Rad51 filaments against Srs2, but facultative for filament formation

    Emilie Ma et al.
    The association of Rad52 with Rad51, while not critical for Rad51 filament formation, is crucial to protect Rad51 filaments from Srs2 translocase activity through the association of Rad52 with complete Rad51 filaments.

    Gating mechanisms during actin filament elongation by formins

    Fikret Aydin et al.
    Formins slow elongation of actin filament by either sterically blocking the addition of actin subunits or flattening the helical twist of the filament end.

    The EMT transcription factor Snai1 maintains myocardial wall integrity by repressing intermediate filament gene expression

    Alessandra Gentile et al.
    The transcription factor Snai1b maintains the myocardial wall integrity by limiting cell extrusions and regulating the intermediate filament gene desmin b.
