DAT is an integral membrane protein that removes dopamine from the synaptic cleft and deposits it into surrounding cells, thus terminating the signal of the neurotransmitter. Dopamine underlies several aspects of cognition, including reward, and DAT facilitates regulation of that signal.
A dopamine agonist is a compound that activates dopamine receptors in the absence of that receptor's physiological ligand, the neurotransmitter dopamine.Dopamine agonists activate signaling pathways through the dopamine receptor and trimeric G-proteins, ultimately leading to changes in gene transcription. dopamine agonist is a compound that activates dopamine receptors in the absence of that receptor's physiological ligand, the neurotransmitter dopamine.
