    Hypocretin neuron-specific transcriptome profiling identifies the sleep modulator Kcnh4a

    Laura Yelin-Bekerman et al.
    Comprehensive gene profiling of the hypothalamic hypocretin neurons, high resolution imaging and behavioral assays have revealed the molecular signature of these versatile neurons and identified a potassium channel that is required for nighttime sleep.

    Molecular mechanism of voltage-dependent potentiation of KCNH potassium channels

    Gucan Dai, William N Zagotta
    A powerful new fluorescence approach elucidates the structural mechanism for a specialized ion channel behavior important for cardiac and neuronal excitability.

    IK1 channels do not contribute to the slow afterhyperpolarization in pyramidal neurons

    Kang Wang et al.
    The slow afterhyperpolarization that follows a burst of action potentials is a powerful regulator of neuronal excitability and is not due to IK1 (KCNN4), a member of the SK channel family.

    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.

    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.

    Dyshomeostatic modulation of Ca2+-activated K+ channels in a human neuronal model of KCNQ2 encephalopathy

    Dina Simkin et al.
    An inducedpluripotent stem cell (iPSC)-based model of KCNQ2-associated developmental epileptic encephalopathy suggests that disease is driven by dyshomeostaic neuronal mechanisms that are downstream of loss of M-current.

    Predominance of cis-regulatory changes in parallel expression divergence of sticklebacks

    Jukka-Pekka Verta, Felicity C Jones
    Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.
