GABRA2 - gamma-aminobutyric acid (GABA) A receptor, alpha 2
Entrez Gene Name: gamma-aminobutyric acid (GABA) A receptor, alpha 2
Synonyms: C630048P16Rik, FLJ97076, Gaba A receptor alpha-2, GABA A RECEPTOR SUBUNIT ALPHA 2, GABRA2, MGC140832

Gene Summary

  • Human (2555): 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 the same protein have been found for this gene. [provided by RefSeq]
  • Rat (289606): may act as subunits in GABA-A receptors with benzodiazepine II binding characteristics [RGD]
