    Transport mechanism of P4 ATPase phosphatidylcholine flippases

    Lin Bai et al.
    A detailed molecular mechanism on lipid flipping from outside leaflet to the inside leaflet of the eukaryotic plasma membrane bilayer.

    Identification of ubiquitin Ser57 kinases regulating the oxidative stress response in yeast

    Nathaniel L Hepowit et al.
    Ser57 phosphorylation of ubiquitin protects the cell during proteotoxic stress.

    Single-cell dynamics of pannexin-1-facilitated programmed ATP loss during apoptosis

    Hiromi Imamura et al.
    Cleavage of pannexin-1 channel by caspases facilitates the loss of intracellular ATP level and attenuates glycolytic metabolism of apoptotic cells.

    Functional exploration of heterotrimeric kinesin-II in IFT and ciliary length control in Chlamydomonas

    Shufen Li et al.
    Experimental and modelling analyses suggest a non-linear scaling relationship between IFT velocity and ciliary length that can be accounted for by limitation of the motors.

    A regulatory pathway that selectively up-regulates elongasome function in the absence of class A PBPs

    Yesha Patel et al.
    Balanced peptidoglycan synthesis requires regulators, including sigma-I and WalKR, that coordinate the diffusive action of class A PBPs and the directional motion of the MreB-directed elongasome.

    Transient protein accumulation at the center of the T cell antigen-presenting cell interface drives efficient IL-2 secretion

    Danielle J Clark et al.
    A membrane-associated, supramolecular protein complex with dynamically changing components, the central supramolecular activation cluster, regulates the generation of the T cell effector cytokine IL-2 depending on its composition.

    RIM is essential for stimulated but not spontaneous somatodendritic dopamine release in the midbrain

    Brooks G Robinson et al.
    Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.

    Presenilin/γ-secretase-dependent EphA3 processing mediates axon elongation through non-muscle myosin IIA

    Míriam Javier-Torrent et al.
    EphA signaling plays dual opposite roles on axon dynamics in neurons, so it inhibits and promotes axon growth through ligand binding and receptor processing, respectively.

    Combinatorial chromatin dynamics foster accurate cardiopharyngeal fate choices

    Claudia Racioppi et al.
    ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
