Function
The function of the GHB receptor appears to be quite different from that of the GABAB receptor. It shares no sequence homology with GABAB, and administration of mixed GHBR/GABAB agonists along with a selective GABAB antagonist or selective agonists for the GHB receptor which are not agonists at GABAB, do not produce a sedative effect, instead causing a stimulant effect followed by convulsions at higher doses, thought to be mediated through increased Na+/K+ current and increased release of dopamine and glutamate.
