An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is a membrane protein with an aqueous pore, meaning it allows soluble materials to travel across the ...

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 ...

This news release is available in German. Ion channels are essential structures of life. Ion channels are specialized pores in the cell membrane and move charged atoms known as ions in and out of ...

A member of an important class of ion channel proteins can transiently rearrange itself into a larger structure with dramatically altered properties, according to a study led by researchers at Weill ...

Researchers from École Polytechnique Fédérale de Lausanne, Switzerland (EPFL) have mapped the molecular workings of potassium ion channels within the brain. The study titled, “A kinetic map of the ...

Cells send electrical impulses throughout the body, but electrophysiologists struggled to tune into these signals until the patch clamp technique was developed. Although biophysicist Bernard Katz from ...
