GHB Receptor - Function

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.
