Gamma-aminobutyric acid receptor subunit alpha-2 is a protein that in humans is encoded by the GABRA2 gene.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.
