GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel. Rho-1 GABA receptor could play a role in retinal neurotransmission.
Subcellular locations: Postsynaptic cell membrane, Cell membrane
Highly expressed in the retina and in a lesser extent in brain, lung and thymus.
