Gamma-aminobutyric acid receptor subunit gamma-2 (GABRG2) is a protein that is part of the gamma-aminobutyric acid (GABA) receptor family, specifically the GABA_A receptor. GABA is the primary inhibitory neurotransmitter in the central nervous system, and its receptors play a crucial role in regulating neuronal excitability. The GABA_A receptor is a pentameric structure, meaning it is composed of five subunits.
