    Full length RTN3 regulates turnover of tubular endoplasmic reticulum via selective autophagy

    Paolo Grumati et al.
    Full length RTN3 homodimerization mediates ER tubules fragmentation and their subsequent delivery to lysosome.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

    Human biallelic MFN2 mutations induce mitochondrial dysfunction, upper body adipose hyperplasia, and suppression of leptin expression

    Nuno Rocha et al.
    Specific human mitofusin 2 mutations induce selective upper body obesity with suppressed leptin expression and severe adipose mitochondrial dysfunction.

    Selective sorting and destruction of mitochondrial membrane proteins in aged yeast

    Adam L Hughes et al.
    A new mitochondrial protein degradation pathway selectively sorts and destroys a subset of the mitochondrial membrane proteome to protect mitochondria in times of stress.

    Neuronal TORC1 modulates longevity via AMPK and cell nonautonomous regulation of mitochondrial dynamics in C. elegans

    Yue Zhang et al.
    Modulating the nutrient sensor TORC1 only in neurons in C. elegans is sufficient to regulate systemic longevity via inter-tissue signals that remodel mitochondria networks in non neuronal cells.

    Mitochondrial biogenesis is transcriptionally repressed in lysosomal lipid storage diseases

    King Faisal Yambire et al.
    Transcription factors KLF2 and ETV1 repress the transcriptional program of mitochondrial biogenesis, resulting in impaired mitochondrial function in lysosomal storage diseases.

    Aurora kinase A localises to mitochondria to control organelle dynamics and energy production

    Giulia Bertolin et al.
    AurkA is imported into mitochondria at interphase, and it induces organelle elongation and enhances ATP production when over-expressed.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

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

    Sora Lee et al.
    Ser57 phosphorylation regulates ubiquitin homeostasis by inhibiting deubiquitylase-mediated recycling and promoting vacuolar degradation.

    Parkin contributes to synaptic vesicle autophagy in Bassoon-deficient mice

    Sheila Hoffmann-Conaway et al.
    The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.
