Drd4 (P51436) - Overview - Molecular Target Synopsis


Drd4, D(4) dopamine receptor
UniProt P51436

Also Known as DRD4_MOUSE, Drd4

Dopamine receptor responsible for neuronal signaling in the mesolimbic system of the brain, an area of the brain that regulates emotion and complex behavior. Activated by dopamine, but also by epinephrine and norepinephrine, and by numerous synthetic agonists and drugs. Agonist binding triggers signaling via G proteins that inhibit adenylyl cyclase (By similarity). Modulates the circadian rhythm of contrast sensitivity by regulating the rhythmic expression of NPAS2 in the retinal ganglion cells (PubMed:24048828). Forms homo- and heterooligomers with DRD2. D4.7 allele exhibits higher affinity for homodimers compared to DRD2 heterodimers, while alleles D42. and 4.4 have similar affinities for both. The interaction with DRD2 may modulate agonist-induced downstream signaling (By similarity). Interacts with CLIC6 (By similarity). Interacts with GPRASP1. May interact with ADORA2A. Interacts with KLHL12.
