Potassium channel blockers are a type of medication used to treat conditions like cardiac arrhythmias. They block the movement of potassium channels in the body, disrupting the body’s electrical ...

Potassium channels are critical structures in biology; they selectively allow potassium ions to pass through the membrane surrounding cells. The precise gating of that channel is essential to its ...

Potassium leak channels are essential to neurophysiological function. Leaks suppress excitability through maintenance of resting membrane potential below the threshold for action potential firing.

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years. Researchers ...
