DRD1
(redirected from D(1A) dopamine receptor)DRD1
A gene on chromosome 5q35.1 that encodes G protein-coupled dopamine receptor D1, which is the most abundant dopamine receptor in the CNS. D1 dopamine receptors stimulate adenylyl cyclase and activate cyclic AMP-dependent protein kinases; they regulate neuronal growth and development, mediate some behavioural responses, and modulate dopamine receptor D2-mediated events.Segen's Medical Dictionary. © 2012 Farlex, Inc.
