Background：Glycine receptors are ligand-gated chloride channels. Channel opening is triggered by extracellular glycine(PubMed:2155780, PubMed:15302677, PubMed:16144831, PubMed:23895467, PubMed:25445488). Channel opening is also triggered by taurine and beta-alanine(PubMed:15302677). Plays a role in the down-regulation of neuronal excitability. Contributes to the generation of inhibitory postsynaptic currents(PubMed:25445488). Plays a role in cellular responses to ethanol(PubMed:23895467).
