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 ...

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their ...

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 new study. The discovery is a ...

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 ...

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 ...
