Gene Gene information from NCBI Gene database.
Entrez ID 2555
Gene name Gamma-aminobutyric acid type A receptor subunit alpha2
Gene symbol GABRA2
Synonyms (NCBI Gene)
DEE78EIEE78
Chromosome 4
Chromosome location 4p12
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 GA
