GHB receptor

Gamma-hydroxybutyrate receptor or GHB receptor is a receptor that binds gamma-Hydroxybutyric acid. Its existence was predicted by observing the action of its agonists that previously were thought to act on GABA-B receptors. The rat GHB receptor was first cloned and characterised in 2003 followed by the human receptor in 2007. It is a G-protein coupled receptor.
