Function

Gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the brain, mediates neuronal inhibition by binding to GABA receptors. The type A GABA receptors are pentameric chloride channels assembled from among many genetic variants of GABA(A) subunits. This gene encodes the gamma 2 subunit of GABA(A) receptor. Mutations in this gene have been associated with epilepsy and febrile seizures. Alternative splicing of this gene results in transcript variants encoding different isoforms.[5]

Interactions

GABRG2 has been shown to interact with GABARAP[6][7][8] and Dopamine receptor D5.[9]
