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

Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.

Serotonin neurons in chronically isolated mice become less responsive to excitatory stimulation, but inhibiting a distinctive calcium-activated potassium channel can restore both neuronal activity and behavior.

Potassium ions enter and leave human sperm cells via a calcium-dependent ion channel that is also pH-independent.

Oligodendrocytes in white matter use Kir4.1 inwardly rectifying potassium channels to prevent extracellular potassium accumulation, enabling neurons to sustain repetitive firing and limiting the initiation of seizures.

The mammalian potassium channel KCa3.1, which is important for T- and B-cell activation, is inhibited by cytoplasmic copper, mediated by a histidine residue (His358) that is phosphorylated to activate the channel.

Type 1 potassium channels alter their composition and localisation to suppress hyper-excitability and neuropathic pain of injured sensory neurons.

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.

A mouse model of human muscle myopathy is used to provide mechanistic insight, identify possible biomarkers of disease, and suggest possible therapeutic strategies to alleviate muscle weakness.

Single-particle cryo-electron microscopy reveals the first subnanometer structure of ATP-sensitive potassium (K_ATP) channels, which provides insight into the structural mechanisms of channel assembly and gating.
