National Center for Biotechnology Information WebG-protein-coupled receptors are bound by a ligand, which activates a type of membrane protein known as G-protein, which then interacts with an ion channel or an enzyme in the plasma membrane. Ion channel-linked receptors work by binding a ligand and then opening a channel across the plasma membrane that allows specific ions to pass through.
