The GABAB receptor forms high order oligomers in cultured hippocampal neurons. (a) Schematic representation of the mGlu2 receptor and the three combinations of untagged and SNAP-tagged GABAB receptor subunits. (b-c) Comparison of the subunits per complex for all GABAB receptor combinations (grey) with the mGlu2 receptor (black) as a function of the expression level (b) or for cells with an expression in the 90–600 subunits/Veff range (c). The number of subunits per complex is higher for the GABAB receptor than for the mGlu2 receptor (p < 0.0001; unpaired, two-sided t-test). Error bars represent SD. Data are from 14–17 independent experiments.
