    A stress assembly that confers cell viability by preserving ERES components during amino-acid starvation

    Margarita Zacharogianni et al.
    Amino-acid starvation leads to the formation of a reversible stress assembly, the Sec body, which is a pro-survival reservoir for components of the ER exit sites.

    The proteasome biogenesis regulator Rpn4 cooperates with the unfolded protein response to promote ER stress resistance

    Rolf M Schmidt et al.
    Endoplasmic reticulum stress in yeast activates not only the UPR but also Rpn4, promoting the clearance of misfolded proteins from the cytosol as part of a modular cross-compartment stress response.

    Engineering ER-stress dependent non-conventional mRNA splicing

    Weihan Li et al.
    Ire1's RNase specificity and its cleavage sites coordination shape the evolutionary specialization of the unfolded protein response.

    Cell-based HTS identifies a chemical chaperone for preventing ER protein aggregation and proteotoxicity

    Keisuke Kitakaze et al.
    Cell-based high-throughput screening identifies IBT21 as a chemical chaperone, that inhibits ER protein aggregation and prevents the cell death caused by a proteotoxin, the aggregation-prone prion protein.

    Accelerated phosphatidylcholine turnover in macrophages promotes adipose tissue inflammation in obesity

    Kasparas Petkevicius et al.
    Obesity leads to increased phosphatidylcholine turnover in adipose tissue macrophages that makes them susceptible to saturated fatty acid-induced inflammation.

    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.

    The critical role of membralin in postnatal motor neuron survival and disease

    Bo Yang et al.
    Membralin mutant mice manifest a severe and early-onset motor neuron disease with defects in endoplasmic reticulum-associated protein degradation.

    Misfolded proteins bind and activate death receptor 5 to trigger apoptosis during unresolved endoplasmic reticulum stress

    Mable Lam et al.
    Death receptor 5 can directly sense misfolded proteins downstream of the endoplasmic reticulum to provide a quality control mechanism that executes apoptosis and prevents further production of misfolded proteins.

    Functional CRISPR screening identifies the ufmylation pathway as a regulator of SQSTM1/p62

    Rowena DeJesus et al.
    FACS-based pooled CRISPR screening is a powerful forward genetic tool to interrogate cellular pathways and targets that modulate protein fate.

    Adaptation to constant light requires Fic-mediated AMPylation of BiP to protect against reversible photoreceptor degeneration

    Andrew T Moehlman et al.
    Tuning of BiP activity by Fic-mediated AMPylation is required for Drosophila photoreceptor plasticity and attenuation of the unfolded protein response.
