Glycine receptors are ligand-gated chloride channels. Channel opening is triggered by extracellular glycine (   ). Channel opening is also triggered by taurine and beta-alanine . Plays a role in synaptic plasticity (By similarity). Contributes to the generation of inhibitory postsynaptic currents, and is involved in the down-regulation of neuronal excitability . Plays a role in cellular responses to ethanol .
