RT "Drosophila melanogaster GRD and LCCH3 subunits form heteromultimeric GABA-
RT gated cation channels.";
RL Br. 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}.
