    DIP2 is a unique regulator of diacylglycerol lipid homeostasis in eukaryotes

    Sudipta Mondal, Priyadarshan Kinatukara ... Rajan Sankaranarayanan
    DIP2 is a conserved protein across fungi and animals that regulates specific diacylglycerol pools by diverting them to storage lipid biosynthesis to enable cellular homeostasis and adaptations.

    Recruitment of clathrin to intracellular membranes is sufficient for vesicle formation

    Cansu Küey, Méghane Sittewelle ... Stephen J Royle
    Clathrin-coated vesicles can be made to form on intracellular membranes using a minimal molecular system, which defines the core vesicle budding machinery.

    The relative binding position of Nck and Grb2 adaptors impacts actin-based motility of Vaccinia virus

    Angika Basant, Michael Way
    The ability of Vaccinia virus to induce actin polymerisation depends on the relative binding position of adaptors within the signalling network activating the Arp2/3 complex.

    The molecular mechanism of load adaptation by branched actin networks

    Tai-De Li, Peter Bieling ... Daniel A Fletcher
    An actin-based Brownian Ratchet enables branched actin networks to generate pushing forces, while a capping protein-based Brownian Ratchet provides force feedback that enables these networks to adapt their architecture in response to changing loads.

    A non-transcriptional function of Yap regulates the DNA replication program in Xenopus laevis

    Rodrigo Meléndez García, Olivier Haccard ... Odile Bronchain
    Yap interacts with Rif1, a major DNA replication timing factor, and functions as a brake to control the DNA replication program in Xenopus early embryos and post-embryonic stem cells.

    Cell Mechanics: Under the hood of a moving cell

    Guillaume Romet-Lemonne
    Experiments using purified proteins reveal how the network of filaments that underlie cell movement becomes denser when pushing against a stronger mechanical force.

    HIF-1α induces glycolytic reprograming in tissue-resident alveolar macrophages to promote cell survival during acute lung injury

    Parker S Woods, Lucas M Kimmig ... Gökhan M Mutlu
    Transcriptomic and bionergetic analysis shows the importance of HIF-1α activation in enabling tissue-resident alveolar macrophages to perform glycolytic metabolism, which prevents their death and attenuates influenza A virus-induced acute lung injury.

    Flagellar energy costs across the tree of life

    Paul E Schavemaker, Michael Lynch
    Prokaryotic and eukaryotic flagella follow a common trend in swimming cost-effectiveness, but eukaryotic flagella are too large for cells with prokaryote volumes, yielding insight into flagellar dissimilarity between taxa.

    Tracking receptor motions at the plasma membrane reveals distinct effects of ligands on CCR5 dynamics depending on its dimerization status

    Fanny Momboisse, Giacomo Nardi ... Anne Brelot
    Combining particle tracking in living cells with statistical analysis demonstrates how the oligomeric organization of cell surface receptor influences their function, a necessary step in the development of drugs targeting specific receptor conformation.

    Pathogenic mutations in the chromokinesin KIF22 disrupt anaphase chromosome segregation

    Alex F Thompson, Patrick R Blackburn ... Jason Stumpff
    Pathogenic mutations in KIF22, which dominantly cause bone dysplasia, improperly activate the motor during anaphase in dividing cells leading to chromosome recongression.
