    Collagen polarization promotes epithelial elongation by stimulating locoregional cell proliferation

    Hiroko Katsuno-Kambe, Jessica L Teo ... Alpha S Yap
    Integrin- and ERK signaling stimulates mammary epithelial cell proliferation when extracellular collagen condenses, causing asymmetric growth of multicellular aggregates that is necessary for elongation during branching morphogenesis.

    Allosteric activation of the nitric oxide receptor soluble guanylate cyclase mapped by cryo-electron microscopy

    Benjamin G Horst, Adam L Yokom ... Michael A Marletta
    The full-length structures of the mammalian nitric oxide receptor reveal the molecular activation steps and a binding site for the prototype of FDA-approved stimulators.

    SARS-CoV2 variant-specific replicating RNA vaccines protect from disease following challenge with heterologous variants of concern

    David W Hawman, Kimberly Meade-White ... Jesse H Erasmus
    A replicating RNA vaccine platform generated significant immunity against SARS-CoV2 in mice and hamsters, and can be updated to target variants of concern.

    Glycan-based shaping of the microbiota during primate evolution

    Sumnima Singh, Patricia Bastos-Amador ... Miguel P Soares
    Ggta1 deletion in mice shapes and reduces the microbiota pathogenicity and probably contributed to the natural selection of GGTA1 loss-of-function mutations in the ancestral primates that gave rise to humans.

    The functional O-mannose glycan on α-dystroglycan contains a phospho-ribitol primed for matriglycan addition

    Jeremy L Praissman, Tobias Willer ... Lance Wells
    Disruption of the LG domain-binding phospho-ribitol-containing O-mannose structures on α-dystroglycan results in congenital muscular dystrophy.

    Oscillatory hyperactivity and hyperconnectivity in young APOE-ɛ4 carriers and hypoconnectivity in Alzheimer’s disease

    Loes Koelewijn, Thomas M Lancaster ... Krish Singh
    Electrophysiology pinpoints brain function abnormalities in young people genetically at risk of developing Alzheimer's disease much later in life, supporting theories of initial hyperconnectivity driving eventual profound disconnection.

    An auto-inhibited state of protein kinase G and implications for selective activation

    Rajesh Sharma, Jeong Joo Kim ... Choel Kim
    The crystal structure of a mammalian protein kinase G reveals contacts between the regulatory and catalytic domains, indicates how cGMP binding alters domain conformations and thus domain:domain interactions, and informs a model for enzyme auto-inhibition and cooperative activation.

    Hsp70-associated chaperones have a critical role in buffering protein production costs

    Zoltán Farkas, Dorottya Kalapis ... Csaba Pál
    Protein biosynthesis and protein quality control jointly determine protein production costs.

    The neuronal architecture of the mushroom body provides a logic for associative learning

    Yoshinori Aso, Daisuke Hattori ... Gerald M Rubin
    A map of the entire array of cell types and potential projections in the mushroom body of the fruit fly brain provides insights into the circuitry that supports learning of stimulus-reward and stimulus–punishment associations.

    Precise assembly of complex beta sheet topologies from de novo designed building blocks

    Indigo Chris King, James Gleixner ... David Baker
    Protein structures with complex topologies can be designed by recombining small independently folded domains.
