    pH- and sodium-induced changes in a sodium/proton antiporter

    Cristina Paulino, Werner Kühlbrandt
    Sodium ions but not protons induce defined helix movements in a sodium/proton antiporter and suggest a mechanism for Na + binding and transport.

    High lumenal chloride in the lysosome is critical for lysosome function

    Kasturi Chakraborty et al.
    Lysosomes are highly enriched in chloride, which is essential for their degradative function.

    Kinetic mechanism of coupled binding in sodium-aspartate symporter GltPh

    SeCheol Oh, Olga Boudker
    Sodium ions control the rates of both substrate binding and dissociation of an archaeal homologue of glutamate transporters in a manner that minimizes binding intermediates and maximizes transport efficiency.

    Structure and transport mechanism of the sodium/proton antiporter MjNhaP1

    Cristina Paulino et al.
    The inward-open and outward-open structures of MjNhaP1 explain the mechanism of electroneutral sodium-proton antiport across the cell membrane.

    A family of fluoride-specific ion channels with dual-topology architecture

    Randy B Stockbridge et al.
    Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.

    Divergent Cl- and H+ pathways underlie transport coupling and gating in CLC exchangers and channels

    Lilia Leisle et al.
    Combined simulations and electrophysiological experiments show that the CLC channels and exchangers form physically distinct and evolutionarily conserved pathways through which Cl- and H+ ions move when crossing biological membranes.

    Agonist-mediated switching of ion selectivity in TPC2 differentially promotes lysosomal function

    Susanne Gerndt et al.
    The lysosomal ion channel TPC2 emerges as an example of an ion channel in which ion selectivity is not fixed but rather agonist-selective.

    Synaptic mitochondria regulate hair-cell synapse size and function

    Hiu-tung C Wong et al.
    Mitochondrial calcium influx plays distinct roles in presynapse formation, function and stability in sensory hair cells.

    Activation of a nucleotide-dependent RCK domain requires binding of a cation cofactor to a conserved site

    Celso M Teixeira-Duarte et al.
    Cations are essential cofactors in the ATP activation mechanism of the KtrAB cation channel and appear to be cofactors of many other nucleotide-dependent RCK domains.

    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.
