    Loss of Frataxin activates the iron/sphingolipid/PDK1/Mef2 pathway in mammals

    Kuchuan Chen et al.
    The iron/sphingolipid/PDK1/Mef2 pathway is activated in mammals upon loss of Frataxin.

    The metal transporter ZIP13 supplies iron into the secretory pathway in Drosophila melanogaster

    Guiran Xiao et al.
    Drosophila ZIP13 (Slc39a13), a presumed zinc importer, is responsible for iron delivery to the secretory pathway.

    Molecular determinants of permeation in a fluoride-specific ion channel

    Nicholas B Last et al.
    The ion-transport pathway of an unconventional bacterial fluoride channel is mapped out through combined crystallographic and functional experiments.

    Ferritinophagy via NCOA4 is required for erythropoiesis and is regulated by iron dependent HERC2-mediated proteolysis

    Joseph D Mancias et al.
    NCOA4, the ferritin autophagy receptor, is regulated by HERC2 in an iron-dependent manner and is critical for red blood cell development.

    Atypical calcium regulation of the PKD2-L1 polycystin ion channel

    Paul G DeCaen et al.
    Outward calcium ion currents desensitize the human PKD2-L1 ion channel via a mechanism that is independent of cytosolic motifs.

    The mitochondrial acyl carrier protein (ACP) coordinates mitochondrial fatty acid synthesis with iron sulfur cluster biogenesis

    Jonathan G Van Vranken et al.
    The essential function of ACP is not related to mitochondrial fatty acid and lipoic acid synthesis, but rather an evolutionarily-conserved role in iron sulfur cluster biogenesis.

    Mechanistic signs of double-barreled structure in a fluoride ion channel

    Nicholas B Last et al.
    Combining crystal structures with single-pore analysis of Fluc-family fluoride channel mutants demonstrates that Fluc channels have two separate fluoride ion permeation pathways within the channel complex.

    Mechanical sensitivity of Piezo1 ion channels can be tuned by cellular membrane tension

    Amanda H Lewis, Jörg Grandl
    Tension is the activating stimulus of Piezo1 mechanosensitive ion channels and resting membrane tension modulates overall channel sensitivity to mechanical stimulation.

    OSCA/TMEM63 are an evolutionarily conserved family of mechanically activated ion channels

    Swetha E Murthy et al.
    A family of proteins (OSCA/TMEM63) that encode mechanosensitive ion channels has been characterized in plants, flies, and mammals.

    A selectivity filter at the intracellular end of the acid-sensing ion channel pore

    Timothy Lynagh et al.
    Sodium selectivity of acid-sensing ion channels is mediated by negatively charged side chains and not by a size-exclusion mechanism.
