Neuronal Receptors (s) having Clusters of the alpha1, and alpha2, alpha3, and gamma2 subunits of the GABAA receptor were found on the somatodendritic membranes of Alpha ganglion cells. Experiments with different combinations of the subunit-specific antibodies showed that the alpha1, alpha2, and alpha3 subunits of the GABA(A) receptor are not colocalized within the same clusters, suggesting that an individual neuron can express several isoforms of the GABAA receptor and that these different isoforms are aggregated at distinct postsynaptic sites as Publication facts
