GABAergic neurons produce gamma-Aminobutyric acid (GABA), which is the main inhibitory neurotransmitter in the mammalian central nervous system (CNS).
GABA is primarily synthesized from glutamate, catalyzed by glutamate decarboxylase (GAD), and is present at 30 - 40% of synapses. GABA induces either Cl- influx or K+ efflux, resulting in hyperpolarized neurons and reduced action potential.
Dysfunction of GABA neurotransmission can result in several disorders, including schizophrenia and epilepsy.
A transporter on the cell membrane that moves GABA into the cell, removing it from the synaptic cleft.

GABAB receptors are metabotropic transmembrane receptors for GABA that are linked via G-proteins to potassium channels. GABAB receptor 1 and GABAB receptor 2 assemble as heterodimers in neuronal membranes.
