MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]
PHENOTYPE: Mice homozygous for a knockout allele are resistant to the anxiolytic effects of diazepam (DZP). Mice homozygous for a different knock-out allele exhibit reduced DZP-induced antihyperalgesia. [provided by MGI curators]
