Although several types of excitable cells exist — including neurons, muscle cells, and touch receptor cells — all of them use ion channel receptors to convert chemical or mechanical messages ...

Ion channels are integral membrane protein assemblies that modulate the flow of ions into and out of a cell or organelle, leading to generation of electrical signals. Opening (gating) of ion ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function ...
