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 ...

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 ...

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 ...
