CC   -!- FUNCTION: Component of the heteropentameric receptor for GABA, the
CC       major inhibitory neurotransmitter in the vertebrate brain. Functions
CC       also as histamine receptor and mediates cellular responses to
CC       histamine. Functions as receptor for diazepines and various
CC       anesthetics, such as pentobarbital; these are bound at a separate
CC       allosteric effector binding site. Functions as ligand-gated chloride
CC       channel. {ECO:0000269|PubMed:26950270}.
CC   -!- SUBUNIT: Binds UBQLN1 (By similarity). Heteropentamer, formed by a
CC       combination of alpha, beta, gamma, delta and rho chains. Interacts with
CC       KCTD8, KCTD12 and KCTD16; this interaction determines the pharmacology
CC       and kinetics of the receptor response, the KCTD proteins markedly
CC       accelerating the GABA-B response, although to different extents (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane
CC       {ECO:0000250|UniProtKB:P50571}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P50571}. Cell membrane

CC   -!- DISEASE: Developmental and epileptic encephalopathy 45 (DEE45)
CC       [MIM:617153]: A form of epileptic encephalopathy, a heterogeneous group
CC       of severe early-onset epilepsies characterized by refractory seizures,
CC       neurodevelopmental impairment, and poor prognosis. Development is
CC       normal prior to seizure onset, after which cognitive and motor delays
CC       become apparent. {ECO:0000269|PubMed:23934111,
CC       ECO:0000269|PubMed:26950270, ECO:0000269|PubMed:27273810}. Note=The
CC       disease is caused by variants affecting the gene represented in this
CC       entry.
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. GABRB1 sub-
CC       subfamily. {ECO:0000305}.
