Background: The human dopamine receptor D1 (DRD1 or D1) is a G-protein- coupled receptor. It is expressed most abundantly in the brain areas such as caudate, nucleus accumbens and olfactory tubercle. The D1 receptor regulates neuronal growth and development, mediates some behavioral responses, and modulates dopamine receptor D2-mediated events.
Application: Functional assays
