What's The Definition Of The Medical Condition Receptors, GABA-B?
Cell surface proteins which bind GAMMA-AMINOBUTYRIC ACID and influence cells via interactions with G-proteins. GABA-B receptors are pharmacologically characterized by their insensitivity to the blocker bicuculline and sensitivity to the agonist L-baclofen. They are found both presynaptically and postsynaptically, and act variously by inhibition of adenylate cyclase, activation of phospholipase A2, activation of potassium channels, and inactivation of voltage-activated calcium channels.
