    Cryo-EM structure of the potassium-chloride cotransporter KCC4 in lipid nanodiscs

    Michelle S Reid et al.
    The structure of the potassium-chloride cotransporter KCC4 provides insight into the basis of ion specificity, transport stoichiometry, and activity regulation for a broadly physiologically and clinically important transporter family.

    Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM

    Gregory M Martin et al.
    Diverse KATP channel inhibitors occupy a common binding pocket and stabilize an interaction between Kir6.2 and SUR1 to allosterically control gating and promote the assembly and trafficking of nascent channels.

    Helical jackknives control the gates of the double-pore K+ uptake system KtrAB

    Marina Diskowski et al.
    The K(+) uptake system KtrAB is controlled by an allosteric mechanism entirely new for membrane channels, which operates the channel gate over a 35 Å distance.

    Evolution of cation binding in the active sites of P-loop nucleoside triphosphatases in relation to the basic catalytic mechanism

    Daria N Shalaeva et al.
    In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.

    ENaC-mediated sodium influx exacerbates NLRP3-dependent inflammation in cystic fibrosis

    Thomas Scambler et al.
    Dysfunction and overexpression of ENaC-mediated sodium influx exacerbates activation of NLRP3-inflammasome mediated inflammation in cells with CF-associated mutations and is modulated by inhibition of these amiloride-sensitive sodium (Na+) channels.
  1. Plain-language Summaries of Research: An inside guide to eLife digests

    Stuart RF King et al.
    After summarizing over 2,400 articles in plain language, the eLife Features team shares what it has learnt about writing and editing for a broad audience.

    Ammonium Transporters: A molecular dual carriageway

    William J Allen, Ian Collinson
    In order to enter a cell, an ammonium ion must first dissociate to form an ammonia molecule and a hydrogen ion (a proton), which then pass through the cell membrane separately and recombine inside.

    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    Structural basis for ion selectivity in TMEM175 K+ channels

    Janine D Brunner et al.
    Structural and functional analysis of a recently discovered non-canonical potassium channel family reveals a unique selectivity filter that is exposed to permeating ions only in the conductive state.
    1. Neuroscience

    The functional organization of excitation and inhibition in the dendrites of mouse direction-selective ganglion cells

    Varsha Jain et al.
    Accurate direction-selective information is present within small sections of the dendrites, raising the possibility that single dendrites utilize parallel processing schemes to process motion information.
