MeSH Heading: Receptors, Adrenergic, alpha-2
Tree Number(s): D12.776.543.750.670.300.300.300.200; D12.776.543.750.695.150.300.300.725; D12.776.543.750.720.330.300.300.200
Unique ID: D018341
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D018341
Scope Note: A subclass of alpha-adrenergic receptors found on both presynaptic and postsynaptic membranes where they signal through Gi-Go G-PROTEINS. While postsynaptic alpha-2 receptors play a traditional role in mediating the effects of ADRENERGIC AGONISTS, the subset of alpha-2 receptors found on presynaptic membranes signal the feedback inhibition of NEUROTRANSMITTER release.
