Background: The human dopamine receptor D5 is a D1-like receptor and its activation stimulates adenylyl cyclase activity. It has a 10-fold higher affinity for dopamine than the D1 receptor. The D5 receptor is expressed in neurons in the limbic regions of the brain, and has been implicated in ADHD and addiction disorders.
