GABRA2 - gamma-aminobutyric acid type A receptor subunit alpha2 Gene
Also Known as DEE78; EIEE78
Species: Homo sapiens
About GABRA2
This gene has 16 transcripts (splice variants), 256 orthologues, 45 paralogues and is associated with 3 phenotypes. Biased expression in brain (RPKM 13.5), kidney (RPKM 1.1) and 1 other tissue.
Summary
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]
