D1 receptor
|
Dopamine receptor that stimulates adenylyl cyclase activity, and has a high affinity for SKF 38393 and its homologs. It is a protien that is encoded, in humans, by the DRD1 gene. The D1 subtype is the most abundant dopamine receptor in the central nervous system. This G-protein coupled receptor stimulates adenylyl cyclase and activates cyclic AMP-dependent protein kinases. D1 receptors are enriched in Caudate-putamen, nucleus accumbens, and olfactory tubercles. These receptors regulate neuronal growth and development, mediate some behavioral responses, and modulate dopamine receptor D2-mediated events. Alternate transcription initiation sites result in two transcript variants of this gene. (adapted from Entrez Gene)

D2 receptor
|
Dopamine receptor is a G-protien coupled receptor that inhibits adenylyl cyclase activity, potentiate calcium evoked release of arachadonic acid, increase potassium channel opening and in some cells decrease intracellular calcium concentrations. D2 receptors have a high affinity for antipsychotic drugs and have higher levels of expression in mammalian hippocampus and hypothalamus. It is encoded by the DRD2 gene in humans and a missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. (adapted from Entrez Gene).

Putamen
|
Subcortical nucleus of telencephalon , which together with the caudate nucleus, forms the striatum. The putamen lies lateral to the internal capsule and medial to the external medullary lamina, and is separated from the caudate nucleus by the fibers of the internal capsule for most of its length, except at its anterior portion.

AMPA-type glutamate-gated cationic channel
|
Cell surface proteins that bind glutamate and directly gate ion channels in cell membranes. AMPA receptors were originally discriminated from other glutamate receptors by their affinity for the agonist AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid). They are probably the most common mediators of fast excitatory synaptic transmission in the central nervous system. Several subtypes have been cloned, and for some types the traditional distinction from kainate receptors may not apply (MSH).
