ML277 exclusively enhances the AO state voltage-sensing domain (VSD)-pore coupling of KCNQ1 channels, providing an effective tool to investigate the voltge-dependent gating and new strategies for treating long QT syndrome.

The PRMT1 protein mediates arginine methylation of KCNQ2 channels to control neuronal excitability.

An integrative structural biology approach provides refined models of the KCNQ1-KCNE1 channel complex, which propose a new mechanism to explain how KCNE1 modulates KCNQ1 channel activation.

The I_Ks potassium channel complex displays functional flexibility that depends on the ratio of its constituent KCNQ1 and KCNE1 protein subunits.

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.

Loss of potassium channel activity from fast-spiking interneurons increases their excitability leading to unexpectedly increased fast excitatory transmission and seizure susceptibility.

Mice that successfully avoid developing tinnitus despite exposure to excessive noise show spontaneous recovery of KCNQ2/3 potassium channel activity associated with a reduction in HCN channel activity in auditory brainstem neurons.

The intermediate state conformation of the human KCNQ1 potassium channel voltage sensor domain was determined, validated, and shown to be conductive under physiological conditions.

Contrary to a generally accepted principle, the pore properties of KCNQ1 channels depend on the states of voltage-sensing domains activation; KCNE1 alters the voltage-sensing domains-pore coupling to modulate KCNQ1 channel properties.

Fatty acid analogues are interesting prototype compounds that may inspire the development of future I_Ks channel activators to treat patients with long QT syndrome caused by diverse arrhythmia-causing mutations in the I_Ks channel.
