    KCNE1 tunes the sensitivity of KV7.1 to polyunsaturated fatty acids by moving turret residues close to the binding site

    Johan E Larsson et al.
    An auxiliary subunit alters the effect of a family of small-molecule openers on a voltage-gated potassium channel by inducing structural re-arrangements that promote protonation of the drug molecule.

    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.
