		+	== Function ==
		+	[[http://www.uniprot.org/uniprot/GLRA1_DANRE GLRA1_DANRE]] Glycine receptors are ligand-gated chloride channels. Channel opening is triggered by extracellular glycine (PubMed:10188956, PubMed:26344198). Plays an important role in the down-regulation of neuronal excitability. Contributes to the generation of inhibitory postsynaptic currents. Channel activity is potentiated by ethanol (By similarity).[UniProtKB:P23415]<ref>PMID:10188956</ref> <ref>PMID:26344198</ref>

		+	== Publication Abstract from PubMed ==
		+	Glycinergic synapses play a central role in motor control and pain processing in the central nervous system. Glycine receptors (GlyRs) are key players in mediating fast inhibitory neurotransmission at these synapses. While previous high-resolution structures have provided insights into the molecular architecture of GlyR, several mechanistic questions pertaining to channel function are still unanswered. Here, we present Cryo-EM structures of the full-length GlyR protein complex reconstituted into lipid nanodiscs that are captured in the unliganded (closed), glycine-bound (open and desensitized), and allosteric modulator-bound conformations. A comparison of these states reveals global conformational changes underlying GlyR channel gating and modulation. The functional state assignments were validated by molecular dynamics simulations, and the observed permeation events are in agreement with the anion selectivity and conductance of GlyR. These studies provide the structural basis for gating, ion selectivity, and single-channel conductance properties of GlyR in a lipid environment.
