Zinc ions are concentrated in the central nervous system and regulate GABAA receptors, which are pivotal mediators of inhibitory synaptic neurotransmission. Zinc ions inhibit GABAA receptor function by an allosteric mechanism that is critically dependent on the receptor subunit composition: αβ subunit combinations show the highest sensitivity, and αβγ isoforms are the least sensitive. Here we propose a mechanistic and structural basis for this inhibition and its dependence on the receptor… CONTINUE READING
