    Helix breaking transition in the S4 of HCN channel is critical for hyperpolarization-dependent gating

    Marina A Kasimova et al.
    The gating polarity of a voltage-gated ion channel is primarily determined by turn propensity of residues at a critical position in the middle of the S4 voltage-sensing helix.

    Dynamic change of electrostatic field in TMEM16F permeation pathway shifts its ion selectivity

    Wenlei Ye et al.
    TMEM16F shifts its ion selectivity in response to change of intracellular Ca2+, membrane potential and ionic strength.

    Calcium-dependent electrostatic control of anion access to the pore of the calcium-activated chloride channel TMEM16A

    Andy KM Lam, Raimund Dutzler
    Ion conduction in the calcium-activated chloride channel TMEM16A is directly regulated by calcium, which binds to a site close to the pore thereby shaping the electrostatics at its intracellular entrance.

    The mechanism of MICU-dependent gating of the mitochondrial Ca2+uniporter

    Vivek Garg et al.
    A comprehensive functional analysis of mitochondrial Ca2+ uniporter (MCU) demonstrates that the auxiliary MICU subunits potentiate Ca2+ transport via MCU.

    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.

    Nucleophile sensitivity of Drosophila TRPA1 underlies light-induced feeding deterrence

    Eun Jo Du et al.
    Electron-donating nucleophilic compounds activate TRPA1 ion channels in fruit flies and mosquitoes, but not humans, making TRPA1 a promising target for insect repellants.

    A sensorimotor model shows why a spectral jamming avoidance response does not help bats deal with jamming

    Omer Mazar, Yossi Yovel
    An elaborated bat-predator model shows that even in high bat-densities, bats can successfully catch flying insects and that changing their signals’ frequency is not necessary for dealing with sensory interference.

    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.

    Epithelial colonies in vitro elongate through collective effects

    Jordi Comelles et al.
    Spontaneous elongation of epithelial colonies is related to the orientation of the mean nematic cell elongation field, as shown and tested with experiments and theory.

    Rapid computations of spectrotemporal prediction error support perception of degraded speech

    Ediz Sohoglu, Matthew H Davis
    Analysis of speech acoustics and human brain activity reveals the neural computations by which listeners combine speech input with prior expectations.
