    Structural basis for mammalian nucleotide sugar transport

    Shivani Ahuja, Matthew R Whorton
    Crystal structures of the mouse CMP-sialic acid transporter in complex with both CMP and CMP-sialic acid reveal the mechanisms of substrate selectivity and transport.

    Structure of the CLC-1 chloride channel from Homo sapiens

    Eunyong Park, Roderick MacKinnon
    A cryo-electron microscopy study of the human CLC-1 chloride ion channel reveals the structural basis of why some CLC proteins function as passive chloride channels whereas others function as an active proton-chloride antiporters.

    Mechanism of Na+-dependent citrate transport from the structure of an asymmetrical CitS dimer

    David Wöhlert et al.
    The high-resolution x-ray structure of an asymmetrical SeCitS dimer, present in the inward- and outward-facing state, provides a complete mechanism of substrate and ion translocation in a sodium-dependent symporter.

    Pharmacological inhibition of cystine–glutamate exchange induces endoplasmic reticulum stress and ferroptosis

    Scott J Dixon et al.
    Erastin and sorafenib inhibit system xc- and induce ER stress, suggesting these may be useful tools for probing the functions of system xc- and its role in inducing ER stress and ferroptosis.

    Cysteine dioxygenase 1 is a metabolic liability for non-small cell lung cancer

    Yun Pyo Kang et al.
    By increasing intracellular cysteine levels, NRF2 engages a tumor suppressive metabolic pathway mediated by cysteine dioxygenase 1.

    Structures in multiple conformations reveal distinct transition metal and proton pathways in an Nramp transporter

    Aaron T Bozzi et al.
    Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.

    Mitochondrial fusion supports increased oxidative phosphorylation during cell proliferation

    Cong-Hui Yao et al.
    In addition to increasing glycolysis, some proliferating cells exhibiting the Warburg effect also increase oxidative phosphorylation through mitochondrial fusion.

    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.
