The amino acid glycine, mediates neuronal inhibition by activating glycine receptors (GlyRs), which are ligand-gated chloride channels of the nicotinic acetylcholine receptor superfamily. GlyRs are known to mediate postsynaptic inhibition in spinal cord, brain stem and some higher brain regions 1 . GlyR is a member of the pentameric Cys-loop ion channel receptor family. Functional Cys-loop receptors comprise homomeric or heteromeric pentameric oligomers with each of the five subunits arranged symmetrically in a ring around a central ion-conducting pore. Several developmentally and regionally regulated GlyR isoforms exist, which result from a differential expression of the GlyR α (α1- α4) and β subunit genes. Each GlyR subunit comprises a large extracellular amino-terminal domain that harbors the ligand-binding sites and the eponymous Cys-loop. This connects to a bundle of four α-helical transmembrane domains (labelled M1–M4) with a large intracellular domain between M3 and M4 and a short extracellular C-terminal tail 2 .
