    Specific presynaptic functions require distinct Drosophila Cav2 splice isoforms

    Christopher Bell, Lukas Kilo ... Stefanie Ryglewski
    Mutually exclusive splicing of two exon pairs of the only Drosophila Cav2 homolog cacophony mediates functional diversity of Cav2 channels in Drosophila.

    Seizures, behavioral deficits, and adverse drug responses in two new genetic mouse models of HCN1 epileptic encephalopathy

    Andrea Merseburg, Jacquelin Kasemir ... Bina Santoro
    Two genetic mouse models for HCN1-linked developmental epileptic encephalopathy display distinct biophysical changes in HCN1 ion channel properties but similar worsening of seizures in response to antiepileptic drugs, thereby recapitulating key features of the human disease.

    The NDNF-like factor Nord is a Hedgehog-induced extracellular BMP modulator that regulates Drosophila wing patterning and growth

    Shu Yang, Xuefeng Wu ... Xiaoyan Zheng
    The NDNF-like factor Nord is a Hedgehog-induced and extracellular-localized dosage-dependent BMP modulator that regulates Drosophila wing patterning and growth.

    A physicochemical perspective of aging from single-cell analysis of pH, macromolecular and organellar crowding in yeast

    Sara N Mouton, David J Thaller ... Liesbeth M Veenhoff
    In mitotically aging yeast cells, the cytosol acidifies, the distances between the organellar membranes decrease dramatically, but crowding on the scale of the average size protein is relatively stable.

    Polysaccharide breakdown products drive degradation-dispersal cycles of foraging bacteria through changes in metabolism and motility

    Astrid Katharina Maria Stubbusch, Johannes M Keegstra ... Glen G D'Souza
    Degradation products of polysaccharides trigger partial population dispersal and alter cellular metabolism, shaping the marine biomass decomposition by foraging bacteria.

    Hierarchical sequence-affinity landscapes shape the evolution of breadth in an anti-influenza receptor binding site antibody

    Angela M Phillips, Daniel P Maurer ... Michael M Desai
    An anti-influenza receptor binding site antibody acquires breadth through hierarchical sets of epistatic mutations distributed across the light and heavy chains, demonstrating how mutations can interact to shape the evolution of antibody breadth in various antigen exposure regimens.

    Molecular basis for dyneinopathies reveals insight into dynein regulation and dysfunction

    Matthew G Marzo, Jacqueline M Griswold ... Steven M Markus
    A mutagenesis screen in budding yeast sheds light on dynein regulation and function, and reveals the molecular basis for disease in patients suffering from neuropathies caused by dynein dysfunction.

    Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

    Colleen N McLaughlin, Maria Brbić ... Hongjie Li
    Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.

    Immunoproteasome functions explained by divergence in cleavage specificity and regulation

    Michael B Winter, Florencia La Greca ... Charles S Craik
    Divergence in immunoproteasome substrate specificity and regulation from the constitutive proteasome impacts peptide cleavage quantity and the cellular capacity of the ubiquitin-proteasome system.

    LRRC23 truncation impairs radial spoke 3 head assembly and sperm motility underlying male infertility

    Jae Yeon Hwang, Pengxin Chai ... Jean-Ju Chung
    LRRC23 is a radial spoke 3 head component essential for normal sperm motility and fertility in mammals.
