GABRA2 is a symbol for the gene, Gamma-aminobutyric acid (GABA) A receptor, alpha 2, in humans. Other names include: Gamma-aminobutyric acid receptor subunit alpha-2; GABA(A) receptor subunit alpha-2; receptor subunit alpha-2; GABA(A) receptor, alpha 2. The encoded protein has an amino acid length of 451 and a mass of 51.3 kDa. GABRA2 is a member of the Ligand-gated ion channel (TC 1.A.9) family, Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily, GABRA2 sub-subfamily. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
