[Q]: It is not serotonin, but the selective reuptake of this compound is inhibited by tiagabine, and it is converted to succinic acid semi-aldehyde, which is subsequently oxidized to succinic acid in the shunt which produces this compound. One receptor for it forms a heteropentameric complex and in immature neurons, this compound facilitates the outward flux of chloride ions, which is why benzodiazepines are ineffective anticonvulsants in newborns. One receptor for it includes a benzodiazepine binding site, and isoguvacine THIP, and muscimol serve as competitive agonists to this molecule. Synthesized by the decarboxylation of glutamic acid, this neurotransmitter is best known for its role as the chief inhibitory neurotransmitter. For 10 points, identify this neurotransmitter, which is often referred to by its four letter acronym.
