D1 dopamine receptor

Patent Pending Dopamine receptor D1, also known as DRD1, is a protein that in humans is encoded by the DRD1 gene. 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.
