RL FEBS Lett. 293:191-194(1991).
CC -!- FUNCTION: GABA, the major inhibitory neurotransmitter in the vertebrate
CC brain, mediates neuronal inhibition by binding to the
CC GABA/benzodiazepine receptor and opening an integral chloride channel.
CC -!- SUBUNIT: Generally pentameric. There are five types of GABA(A) receptor
CC chains: alpha, beta, gamma, delta, and rho.
CC -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane; Multi-pass membrane
CC protein. Cell membrane; Multi-pass membrane protein.
CC -!- PTM: May be palmitoylated. {ECO:0000250}.
CC -!- MISCELLANEOUS: This subunit carries the benzodiazepine binding site.
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. GABRG3 sub-
CC subfamily. {ECO:0000305}.
