Figure 1From: In silico comparative genomic analysis of GABAA receptor transcriptional regulation(a) GABA A receptor subunit composition (b) GABA A receptor gene clusters. (a) Two α, two β and one γ subunit surround a central channel, with a GABA binding site located at each α-β interface. (b) Gene order, intergenic distance and the head-to-head orientation of the α and β subunit genes are conserved in each cluster. After Russek [8]Back to article page
