    The isolated voltage sensing domain of the Shaker potassium channel forms a voltage-gated cation channel

    Juan Zhao, Rikard Blunck
    Expression of the isolated voltage sensing domain significantly alters its structural conformation as well as its gating kinetics, indicating the importance of studying the biological assembly in its entirety.

    Counteracting suppression of CFTR and voltage-gated K+ channels by a bacterial pathogenic factor with the natural product tannic acid

    Yajamana Ramu et al.
    Tannic acid acts as an ‘antidote’ against the negative effects of a bacterial enzyme, which can both aggravate cystic fibrosis and enable the anthrax bacteria to evade the immune responses elicited by a typical live vaccine.

    Insights into electrosensory organ development, physiology and evolution from a lateral line-enriched transcriptome

    Melinda S Modrell et al.
    An unbiased transcriptomic approach reveals that developing paddlefish electrosensory organs express genes essential for mechanosensory hair cell development and synaptic transmission, and identifies candidates for mediating electroreceptor development and function.

    Atomic mutagenesis in ion channels with engineered stoichiometry

    John D Lueck et al.
    Building on previous work (Pless, 2013), we argue that side-chain 'flip out' is a key event in potassium channel C-type inactivation, and propose a new method for encoding multiple noncanonical amino acids and controlling protein stoichiometry.

    Sculpting ion channel functional expression with engineered ubiquitin ligases

    Scott A Kanner et al.
    Engineered E3 ubiquitin ligases are utilized to elucidate mechanisms underlying ubiquitin regulation of membrane proteins, and to achieve robust post-translational functional knockdown of ion channels.

    Proximal clustering between BK and CaV1.3 channels promotes functional coupling and BK channel activation at low voltage

    Oscar Vivas et al.
    Super-resolution imaging reveals a novel multi-channel arrangement that explains how big potassium (BK) channel activation closely tracks the opening of low-voltage-activated L-type calcium channels.
