GABA_A Rγ2 Background Information
GAD-65 and GAD-67, glutamate decarboxylases, function to catalyze the production of GABA (gamma-aminobutyric acid). In the central nervous system, GABA functions as the main inhibitory transmitter by increasing a Cl- (chloride) conductance that inhibits neuronal firing. GABA has been shown to activate both ionotropic (GABAA) and metabotropic (GABAB) receptors, as well as a third class of receptors called GABAC. The © subunit of GABAA receptors are important for benzodiazepine binding and modulation of GABA-mediated Cl- current. GABAA R©2 is a 467 amino acid mulit-pass membrane protein localized to the postsynaptic cell membrane. Present as a pentamer with other GABAA receptor chains (å, ∫, ©, ∂ and r), the GABAA ligand-gated Cl- channels selectively complex with D5DR to enable mutual inhibitory functional interactions between the two receptor systems. Defects in the gene encoding GABAA R©2 have been found to be the cause of childhood absence epilepsy type 2, familial febrile convulsions type 8, generalized epilepsy with febrile seizures plus type 3 and severe myoclonic epilepsy in infancy.
