RX PubMed=11178872; DOI=10.1006/mcne.2000.0934; RA Pierce K.D., Handford C.A., Morris R., Vafa B., Dennis J.A., RA Healy P.J., Schofield P.R.; RT "A nonsense mutation in the alpha1 subunit of the inhibitory glycine RT receptor associated with bovine myoclonus."; RL Mol. Cell. Neurosci. 17:354-363(2001). CC -!- FUNCTION: Glycine receptors are ligand-gated chloride channels. CC Channel opening is triggered by extracellular glycine. Channel CC opening is also triggered by taurine and beta-alanine. Channel CC characteristics depend on the subunit composition; CC heteropentameric channels are activated by lower glycine levels CC and display faster desensitization (By similarity). Plays an CC important role in the down-regulation of neuronal excitability CC (PubMed:11178872). Contributes to the generation of inhibitory CC postsynaptic currents. Channel activity is potentiated by ethanol CC (By similarity). Potentiation of channel activity by intoxicating CC levels ot ethanol contribute to the sedative effects of ethanol CC (By similarity). {ECO:0000250|UniProtKB:P23415, CC ECO:0000250|UniProtKB:Q64018, ECO:0000269|PubMed:11178872}. CC -!- SUBUNIT: Homopentamer (in vitro). Interacts with GLRB to form CC heteropentameric channels; this is probably the predominant form CC in vivo. Heteropentamer composed of two GLRA1 and three GLRB. CC Heteropentamer composed of three GLRA1 and two GLRB. Both CC homopentamers and heteropentamers form functional ion channels, CC but their characteristics are subtly different. CC {ECO:0000250|UniProtKB:P23415}. CC -!- SUBCELLULAR LOCATION: Cell junction, synapse, postsynaptic cell CC membrane {ECO:0000250|UniProtKB:Q64018}; Multi-pass membrane CC protein {ECO:0000250|UniProtKB:Q64018}. Cell junction, synapse CC {ECO:0000250|UniProtKB:Q64018}. Perikaryon CC {ECO:0000269|PubMed:11178872}. Cell projection, dendrite CC {ECO:0000250|UniProtKB:Q64018}.

CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=a; CC IsoId=P57695-1; Sequence=Displayed; CC Name=b; CC IsoId=P57695-2; Sequence=VSP_021141; CC -!- TISSUE SPECIFICITY: Detected on spinal cord neurons (at protein CC level). Detected in spinal cord. {ECO:0000269|PubMed:11178872}. CC -!- DOMAIN: The channel pore is formed by pentameric assembly of the CC second transmembrane domain from all five subunits. Channel CC opening is effected by an outward rotation of the transmembrane CC domains that increases the diameter of the pore. CC {ECO:0000250|UniProtKB:O93430}. CC -!- DISEASE: Note=Defects in GLRA1 are the cause of inherited CC congenital myoclonus of Poll Hereford calves. It is an autosomal CC recessive disease characterized by hyperesthesia and myoclonic CC jerks of the skeletal musculature that occur both spontaneously CC and in response to sensory stimuli. {ECO:0000269|PubMed:11178872}. CC -!- MISCELLANEOUS: The alpha subunit binds strychnine. CC {ECO:0000305|PubMed:11178872}. CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) CC family. Glycine receptor (TC 1.A.9.3) subfamily. GLRA1 sub- CC subfamily. {ECO:0000305}.
