Gamma-aminobutyric acid (GABA) B receptor 1 (GABAB1) is a G-protein coupled receptor subunit encoded by the GABBR1 gene.Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the mammalian central nervous system. GABA exerts its effects through ionotropic [GABA(A/C)] receptors to produce fast synaptic inhibition and metabotropic [GABA(B)] receptors to produce slow prolonged inhibitory signals.
