J. Pharmacol. 142:409-413(2004). CC -!- FUNCTION: GABA, an inhibitory neurotransmitter, mediates neuronal CC inhibition by binding to the GABA receptor and opening an integral CC chloride channel. Combines with the ligand-gated ion channel subunit CC GRD to form cation-selective GABA-gated ion channels when coexpressed CC in Xenopus laevis oocytes. {ECO:0000269|PubMed:15148245}. CC -!- SUBUNIT: Generally pentameric. There are five types of GABA(A) receptor CC chains: alpha, beta, gamma, delta, and rho. Interacts with Grd (alpha CC chain). {ECO:0000269|PubMed:15148245}. CC -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane; Multi-pass membrane CC protein. Cell membrane; Multi-pass membrane protein. CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family. CC Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. {ECO:0000305}.
