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 ...

Researchers have discovered a new mechanism for potassium channel inhibitor entry, which could improve the specificity of drugs targeting the channel. Upon binding to calcium ions, BK channels allow ...

Following this design principle, the researchers create angstrom-scale pores in bi-layer graphene sheets, and decorate the two pore edges with twisted rings of carbonyl groups. The artificial ion ...

Underlying every thought, heartbeat and movement are ion channels, busily conducting high-speed streams of ions into cells, like subway trains coursing through tunnels. Ion channels span the cellular ...

Intrigued by the properties of ion channel proteins commonly observed in cells, researchers have developed the first synthetic mechanosensitive potassium channel using a newly developed aromatic ...

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 ...
