WebBenzodiazepine receptors, which are found on postsynaptic nerve endings in the central nervous system (CNS), are part of the GABA receptor complex. GABA is the primary inhibitory neurotransmitter of the CNS. The GABA receptor complex is composed of two α-subunits and two β-subunits. The α-subunits are the binding sites for benzodiazepines. WebGABAAreceptors are pentameric ligand-gated ion channels that mediate most fast neuronal inhibition in the brain. In addition to their important physiological roles, they are noteworthy in their rich pharmacology; prominent drugs used for anxiety, insomnia, and general anesthesia act through positive modulation of GABAAreceptors.
