NCIt definition : D(1A) dopamine receptor (446 aa, 49 kDa) is encoded by the human DRD1 gene. This
protein is involved in neurotransmitter-dependent G protein-coupled receptor signaling.;
NCIt note : Dopamine Receptor D1, encoded by the human DRD1 gene, 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. It regulates
neuronal growth and development, mediates some behavioral responses, and modulates
dopamine receptor D2-mediated events. Alternate transcription initiation sites result
in two transcript variants of this gene.;
