    AKT isoforms have distinct hippocampal expression and roles in synaptic plasticity

    Josien Levenga, Helen Wong ... Charles A Hoeffer
    Three distinct AKT isoforms are found in the brain and show dissimilar patterns of expression, differential roles in the expression of synaptic plasticity, and different roles in neuronal signaling.

    The structure of the COPI coat determined within the cell

    Yury S Bykov, Miroslava Schaffer ... John AG Briggs
    Cryo-electron tomography of COPI vesicles in the Golgi reveals coat structure, disassembly dynamics, cargo binding, and morphological variability.

    Deciphering caveolar functions by syndapin III KO-mediated impairment of caveolar invagination

    Eric Seemann, Minxuan Sun ... Britta Qualmann
    Mice lacking the membrane-shaping protein syndapin III show severe reduction of caveolae reminiscent of human caveolinopathies but maintain plasma membrane-associated caveolar coats proteins and thereby unveil physiological impairments associated with lack of invaginated caveolae.

    Stimulation of hair follicle stem cell proliferation through an IL-1 dependent activation of γδT-cells

    Pedro Lee, Rupali Gund ... Colin Jamora
    Wounded epidermal keratinocytes emit a signal that activates a specialized T-cell in the skin, leading to an increase in hair follicle stem cell numbers that contributes to tissue repair.

    Bacterial fumarase and L-malic acid are evolutionary ancient components of the DNA damage response

    Esti Singer, Yardena BH Silas ... Ophry Pines
    The dual function of an ancient prokaryotic enzyme, which is linked to specific metabolite signals, may have been the evolutionary driving force behind its dual localization in eukaryotes.

    Phosphatidylinositol 4,5-bisphosphate optical uncaging potentiates exocytosis

    Alexander M Walter, Rainer Müller ... Jakob Balslev Sørensen
    Increasing PI(4,5)P2 on a sub-second timescale using a novel, membrane-permeant UV activatable PI(4,5)P2 molecule augments exocytosis which requires the PI(4,5)P2 interacting exocytotic proteins Munc13-2 and synaptotagmin-1.

    Time-gated detection of protein-protein interactions with transcriptional readout

    Min Woo Kim, Wenjing Wang ... Alice Y Ting
    A light-dependent two-hybrid tool with transcriptional readout detects multiple protein-protein interactions in living mammalian cells with high signal-to-background ratios and enables genetic selections.

    Ubiquitin turnover and endocytic trafficking in yeast are regulated by Ser57 phosphorylation of ubiquitin

    Sora Lee, Jessica M Tumolo ... Jason A MacGurn
    Ser57 phosphorylation regulates ubiquitin homeostasis by inhibiting deubiquitylase-mediated recycling and promoting vacuolar degradation.

    Cyclin A/Cdk1 modulates Plk1 activity in prometaphase to regulate kinetochore-microtubule attachment stability

    Ana Maria G Dumitru, Scott F Rusin ... Duane A Compton
    Quantitative phosphoproteomics defines the substrates for Cyclin A/Cdk1 kinase during early mitosis and follow up studies validate that one identified substrate, MYPT1, influences the stability of k-MT attachments by regulating Plk1.
