Dopamine receptor D1, also known as DRD1, is a protein that in humans is encoded by the DRD1gene.
Function
This gene encodes the D1 subtype of the dopamine receptor. The D1 subtype is the most abundant dopamine receptor in the central nervous system. This G protein-coupled receptor stimulates adenylate cyclase and indirectly activates cyclic AMP-dependent protein kinases. D1 receptors regulate neuronal growth and development, mediate some behavioral responses, and modulate dopamine receptor D2-mediated events. Alternative transcription initiation sites result in two transcript variants of this gene.
There are a number of ligands selective for the D1 receptors. To date, most of the known ligands are based on dihydrexidine or the prototypical benzazepine partial agonist SKF-38393 (one derivative being the prototypical antagonist SCH-23390). D1 receptor has a high degree of structural homologine to another dopamine receptor, D5, and they both bind similar drugs. As a result, none of the known ligands is selective for the D1 vs. the D5 receptor, but the benzazepines generally are more selective for the D1 and D5 receptors versus the D2-like family. Some of the benzazepines have high intrinsic activity whereas others do not.
Specifically, sugar increases the concentration of a type of excitatory receptor called D1, but decreases another receptor type called D2, which is inhibitory ... midbrain dopamine receptors like before.
Tavapadon is the first and only selective D1/D5 receptor partial agonist in development for Parkinson’s disease and is currently being studied as a once-daily medicine for use as both a monotherapy and as an adjunctive therapy to LD.
“Instead, a drug’s effect on the other striatal neuron type, the one that expresses D1 dopamine receptors, is more predictive of whether they actually work.” ... receptors, called cholinergic receptors.
Specifically, they looked at the activity of dopamine-sensitive neurons, focusing on those expressing dopamine D1 and D2 receptors, which play different roles in movement regulation.

Through meticulous computer-aided simulations, researchers have uncovered MIRA1a's predicted ability to initiate a response at three pivotal receptors in the brain— Serotonin 1a (5-HT1a), Serotonin 2c (5-HT2c), and Dopamine D1 receptors.
Two trimeric receptor complexes (IL-6/IL-6Rα/gp130) homodimerize; IL-6 of one trimeric complex binds to the D1 domain of gp130 of the second trimeric complex, forming a signal transducing hexameric receptor complex[8].
