Ligand-gated ion channels are a type of transmembrane protein that form ion channels in the membrane of cells and open or close in response to the binding of a specific chemical messenger or ligand (such as a neurotransmitter). When a ligand binds to the receptor site on the channel, it induces a conformational change in the channel protein that allows ions to flow across the membrane.
