GABRA3 is a gene that encodes the gamma-aminobutyric acid (GABA) type A receptor subunit alpha3. GABA receptors are the major inhibitory neurotransmitter receptors in the central nervous system (CNS) and play a crucial role in regulating neuronal excitability and synaptic transmission. The GABRA3 protein is part of the pentameric structure that forms the GABA A receptor, which consists of five subunits.
