    Ezrin defines TSC complex activation at endosomal compartments through EGFR–AKT signaling

    Giuliana Giamundo, Daniela Intartaglia ... Ivan Conte
    Ezrin controls endo-lysosomal signaling by maintaining TSC inhibition through EGFR signaling, activating mTORC1, and inhibiting lysosomal function, unveiling a critical endosome–lysosome network essential for autophagy and cellular homeostasis.

    A molecular proximity sensor based on an engineered, dual-component guide RNA

    Junhong Choi, Wei Chen ... Jay Shendure
    In P3 editing, molecular interactions are sensed and converted directly into genome editing events, which may be useful for biological recording and synthetic molecular circuits deployed in living cells.

    Interleukin-1 prevents SARS-CoV-2-induced membrane fusion to restrict viral transmission via induction of actin bundles

    Xu Zheng, Shi Yu ... Guangxun Meng
    Interleukin-1 activates RhoA/ROCK signaling, which drives the enrichment of actin bundles at the cell-cell junctions, preventing SARS-CoV-2 spreading via syncytia formation.

    Decoding phase separation of prion-like domains through data-driven scaling laws

    M Julia Maristany, Anne Aguirre Gonzalez ... Jerelle A Joseph
    Phase diagrams for 140 variants of prion-like low-complexity domains are computed to establish scaling laws that quantify the impact of amino acid mutations on the thermodynamic stability of condensates.

    SERBP1 interacts with PARP1 and is present in PARylation-dependent protein complexes regulating splicing, cell division, and ribosome biogenesis

    Kira Breunig, Xuifen Lei ... Luiz O Penalva
    SERBP1 is associate with protein complexes regulating splicing, cell division, and ribosomal biogenesis that likely depend on G quadruplex (G4) binding and polyADP-ribosylation (PARylation) for their assembly and function.

    Non-destructive in situ monitoring of structural changes of 3D tumor spheroids during the formation, migration, and fusion process

    Ke Ning, Yuanyuan Xie ... Ling Yu
    A piece of first-surface mirror for side-view observation enables non-destructive in situ monitoring of structural changes of 3D tumor spheroids during the formation, migration, and fusion process.
