Structural basis of the activation of a metabotropic GABA receptor

WebDopamine receptors are metabotropic receptors that are found predominantly in the CNS. 4.2.3. Serotonin and Histamine. The three catecholamines mentioned above are actually a subset of a larger group of neurotransmitters called monoamines because they have a single amino group connected to an aromatic ring by a two-carbon chain. Webrinic receptors the metabotropic class. Glutamate, GABA, acetylcholine, and many other ligands activate both metab-otropic and ionotropic receptors [1].
