    Proteasome dysfunction triggers activation of SKN-1A/Nrf1 by the aspartic protease DDI-1

    Nicolas J Lehrbach, Gary Ruvkun
    Post-translational processing of the SKN-1A/Nrf1 transcription factor regulates proteasome expression.

    A druggable secretory protein maturase of Toxoplasma essential for invasion and egress

    Sunil Kumar Dogga et al.
    An aspartyl protease is essential for the lytic cycle of Toxoplasma gondii and is involved in the maturation of proteins critical for invasion and egress, and it can be targeted selectively with an ethylamine scaffold based peptidomimetic inhibitor.

    The aspartyl protease DDI2 activates Nrf1 to compensate for proteasome dysfunction

    Shun Koizumi et al.
    Peptidase activity of DDI2 is required to activate Nrf1 in order to enable proteasome recovery in response to proteasome inhibition.

    An aspartyl protease defines a novel pathway for export of Toxoplasma proteins into the host cell

    Michael J Coffey et al.
    The Toxoplasma parasite requires an enzyme called ASP5 to cleave proteins for export into host cells.

    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    Cyclin-dependent kinase 5 (CDK5) regulates the circadian clock

    Andrea Brenna et al.
    Cyclin-dependent kinase 5 regulates the circadian clock involving phosphorylation of the PER2 protein.

    Brain-specific Drp1 regulates postsynaptic endocytosis and dendrite formation independently of mitochondrial division

    Kie Itoh et al.
    Genetic and cell biological analyses reveal a new role of Drp1 in postsynaptic endocytosis during brain development beyond mitochondrial division GTPase.

    Structural basis for isoform-specific kinesin-1 recognition of Y-acidic cargo adaptors

    Stefano Pernigo et al.
    X-ray crystallography reveals how kinesin-1 recognises a novel class of cargo adaptor motifs in an isoform-specific manner.

    Structural basis of ribosomal peptide macrocyclization in plants

    Joel Haywood et al.
    The first crystal structure of an active plant asparaginyl endopeptidase reveals a tetrahedral intermediate state in its active site, which may help to explain why these enzymes have been independently recruited to perform peptide macrocyclization.

    Presenilin mutations deregulate mitochondrial Ca2+ homeostasis and metabolic activity causing neurodegeneration in Caenorhabditis elegans

    Shaarika Sarasija et al.
    In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.
