    Identification of a transporter complex responsible for the cytosolic entry of nitrogen-containing bisphosphonates

    Zhou Yu et al.
    Identification of a transporter complex comprised of SLC37A3 and ATRAID is required for nitrogen-containing bisphosphonates to enter the cytosol from lysosomes and exert their therapeutic effects on bone.

    Symmetric exchange of multi-protein building blocks between stationary focal adhesions and the cytosol

    Jan-Erik Hoffmann et al.
    In the cytosol, the proteins constituting cell-matrix adhesion sites form multi-protein building blocks which enter and leave these sites unaltered, thereby contributing to their rapid and correct self-assembly.

    Bone-Targeting Drugs: From vesicle to cytosol

    Michael J Rogers, Marcia A Munoz
    Drugs called bisphosphonates are used to treat a range of bone diseases, but how do they reach the enzymes that are their target?

    Structural basis of phosphatidylcholine recognition by the C2–domain of cytosolic phospholipase A2α

    Yoshinori Hirano et al.
    The C2-domain of cytoplasmic phospholipase A2α is structurally designed to target PC-rich membrane regions to increase the enzymatic efficiency of the catalytic domain, which prefers PCs with polyunsaturated acyl chains.

    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.

    Proteomic mapping of cytosol-facing outer mitochondrial and ER membranes in living human cells by proximity biotinylation

    Victoria Hung et al.
    One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

    Rare missense variants in the human cytosolic antibody receptor preserve antiviral function

    Jingwei Zeng et al.
    Studying the impact of natural variation on a key immune gene highlights how focusing on a single wild-type sequence overlooks that rare variants cause the most disease.

    Cytosolic Hsp70 and co-chaperones constitute a novel system for tRNA import into the nucleus

    Akira Takano et al.
    A major cytoplasmic chaperone, Ssa2p, acts as a nuclear import carrier for tRNAs upon nutrient starvation in Saccharomyces cerevisiae.

    Voltage-dependent dynamics of the BK channel cytosolic gating ring are coupled to the membrane-embedded voltage sensor

    Pablo Miranda et al.
    Allosteric modulation of BK channels, vital for the physiology of nerve, muscle and endocrine cells, is determined by direct coupling between gating ring RCK1 domains and the voltage sensor function.
