    A new family of StART domain proteins at membrane contact sites has a role in ER-PM sterol transport

    Alberto T Gatta et al.
    A new family of sterol-specific lipid transfer proteins has been found that anchors in the endoplasmic reticulum; some of these proteins stretch across membrane contacts and mediate sterol traffic from the plasma membrane.

    GRAM domain proteins specialize functionally distinct ER-PM contact sites in human cells

    Marina Besprozvannaya et al.
    Functionally distinct ER-PM domains in human cells are defined by conserved GRAM domain containing proteins.

    Miga-mediated endoplasmic reticulum–mitochondria contact sites regulate neuronal homeostasis

    Lingna Xu et al.
    Increasing endoplasmic reticulum (ER)–mitochondria contact sites leads to neurodegeneration.

    An efficient targeted nuclease strategy for high-resolution mapping of DNA binding sites

    Peter J Skene, Steven Henikoff
    CUT&RUN (Cleavage Under Targets & Release Using Nuclease) profiles antibody-targeted DNA-binding proteins in situ with high resolution and low background, providing a simple, robust and scalable alternative to chromatin immunoprecipitation.

    Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria

    FoSheng Hsu et al.
    Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.

    ER-associated mitochondrial division links the distribution of mitochondria and mitochondrial DNA in yeast

    Andrew Murley et al.
    Sites at which mitochondria contact the endoplasmic reticulum co-localize the replication of mitochondria and their DNA to help ensure that DNA is distributed appropriately between the newly formed organelles in cells.

    A crystal structure of a collaborative RNA regulatory complex reveals mechanisms to refine target specificity

    Chen Qiu et al.
    A Caenorhabitis elegans RNA-binding protein, FBF-2, modulates RNA sequence motif recognition through conformational change and partner protein interaction.

    Aim24 and MICOS modulate respiratory function, tafazzin-related cardiolipin modification and mitochondrial architecture

    Max Emanuel Harner et al.
    Interactions between Aim24 and the mitochondrial outer and inner membrane contact site complex (MICOS) are essential for mitochondrial ultrastructure, lipid composition and oxidative phosphorylation.

    Movement of accessible plasma membrane cholesterol by the GRAMD1 lipid transfer protein complex

    Tomoki Naito et al.
    GRAMD1 proteins sense a transient expansion of the accessible pool of plasma membrane cholesterol and facilitate its transport to the endoplasmic reticulum at ER-PM contact sites.

    Human VPS13A is associated with multiple organelles and influences mitochondrial morphology and lipid droplet motility

    Wondwossen M Yeshaw et al.
    VPS13A is associated with the endoplasmic reticulum, mitochondria and lipid droplets and is required for cellular processes that require interaction between these organells.
