    Identification and dynamics of the human ZDHHC16-ZDHHC6 palmitoylation cascade

    Laurence Abrami et al.
    Cycles of palmitoylation-depalmitoylation by an upstream palmitoyltransferase allow precise tuning of DHHC6 activity, which in turn regulates the abundance and function of key ER proteins involved in protein folding, degradation, ER architecture and calcium homeostasis.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong et al.
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

    Translation attenuation by minocycline enhances longevity and proteostasis in old post-stress-responsive organisms

    Gregory M Solis et al.
    Directly targeting the ribosome to attenuate translation partly mimics the integrated stress response, increasing lifespan and preserving protein folding capacity even in older individuals with dysfunctional stress response signaling.

    New insights into the cellular temporal response to proteostatic stress

    Justin Rendleman et al.
    A time-resolved analysis of protein and RNA concentrations and interactions during proteostasis stress highlights the dominant role of translation regulation and a shift of energy metabolism.

    VCP-dependent muscle degeneration is linked to defects in a dynamic tubular lysosomal network in vivo

    Alyssa E Johnson et al.
    The AAA-ATPase VCP sustains sarcoplasmic proteostasis, in part, by controlling autophagosome-lysosome fusion and the integrity of a dynamic tubular lysosomal network.

    Sterol homeostasis requires regulated degradation of squalene monooxygenase by the ubiquitin ligase Doa10/Teb4

    Ombretta Foresti et al.
    Parallel branches of the ERAD pathway regulate sterol synthesis at multiple steps via feedback inhibition.

    Dengue viruses cleave STING in humans but not in nonhuman primates, their presumed natural reservoir

    Alex C Stabell et al.
    An analysis of innate immunity reveals why dengue viruses do not reach high titers in primate laboratory models, even though they emerged through zoonotic transmission from primate reservoirs.

    ERα promotes murine hematopoietic regeneration through the Ire1α-mediated unfolded protein response

    Richard H Chapple et al.
    Estrogen is a systemic factor that promotes hematopoietic regeneration by activating the unfolded protein responses.

    Cell type-specific transcriptomics of hypothalamic energy-sensing neuron responses to weight-loss

    Fredrick E Henry et al.
    Cell type-specific transcriptomics in energy homeostasis neurons has identified hundreds of genes and multiple signaling pathways that are regulated by weight loss in mice, as well as several previously unexamined genes that can regulate appetite and body weight.

    IRBIT controls apoptosis by interacting with the Bcl-2 homolog, Bcl2l10, and by promoting ER-mitochondria contact

    Benjamin Bonneau et al.
    IRBIT and the Bcl-2 homolog Bcl2l10 form a complex at the endoplasmic reticulum that controls Ca2+ signaling, however IRBIT turns into an apoptosis facilitator following stress and inhibits anti-apoptotic activity of Bcl2l10.
