The diverse physiological actions of dopamine are mediated by at least five distinct G protein-coupled receptor subtypes. Two D1-like receptor subtypes (D1 and D5) couple to the G protein Gs and activate adenylyl cyclase. The other receptor subtypes belong to the D2-like subfamily (D2, D3, and D4) and are prototypic of G protein-coupled receptors that inhibit adenylyl cyclase and activate K+ channels. The genes for the D1 and D5 receptors are intronless, but pseudogenes of the D5 exist. The D2… 

Figures and Tables from this paper

Dopamine receptors and hypertension
TLDR
The molecular basis for dopamine receptor dysfunction in hypertension is being investigated, and may involve an abnormal posttranslational modification of the dopamine receptor.
Dopamine receptor expression and function in the normal and pathological hypothalamus-pituitary-adrenal axis
TLDR
Dopamine receptors belong to the family of seven transmembrane domain G protein-coupled receptors and include five different receptor subtypes, named D1-Ds, which suggests the existence of two different groups of receptors: D1 and D5 receptors, associated to a stimulatory function, and Dz-like, including Dz, D3 and D4 receptors,associated to an inhibitory function.
The D2s dopamine receptor stimulates phospholipase D activity: a novel signaling pathway for dopamine.
TLDR
A novel signaling pathway for the D2s is described, which is the activation of phospholipase D (PLD), which was found to correlate with the presence of a specific protein kinase C isoform, PKCepsilon, indicating that the stimulation of PLD may involve Rho family members.
Voltage sensitivity of dopamine D2-like receptors
TLDR
The findings presented in this thesis suggest that the dopamine D2-like receptors are differentially affected by voltage, demonstrating the relevance of GPCR voltage sensitivity to dopaminergic signalling, and reveals new details about the mechanism of voltage sensitive agonism.
Evidence for Noncanonical Neurotransmitter Activation: Norepinephrine as a Dopamine D2-Like Receptor Agonist
TLDR
A careful comparison between dopamine and norepinephrine in their possible activation of all D2-like receptors, including the two D2R isoforms and the most common D4R polymorphic variants is attempted.
The Physiology, Signaling, and Pharmacology of Dopamine Receptors
TLDR
D dopamine receptor classification, their basic structural and genetic organization, their distribution and functions in the brain and the periphery, and their regulation and signal transduction mechanisms are discussed.
Dopamine D1 receptors, regulation of gene expression in the brain, and neurodegeneration.
TLDR
The present paper focuses on a review of the effects of stimulation of DA D1 receptors on diverse signal transduction pathways and gene expression patterns in the brain and the possible involvement of the DA D 1 receptors in DA-mediated toxic effects observed both in vitro and in vivo.
The neurobiology of dopamine receptors: evolution from the dual concept to heterodimer complexes
TLDR
This paper summarized recent data, reported by different research groups, suggesting that the dopamine (DA) D1 receptor forms heteromers with receptors of the same family and with structurally and functionally divergent receptors, which underlies an unexpected level of diversity within this receptor family.

The renal dopamine receptors.
TLDR
Dopamine is an endogenous catecholamine that modulates many functions including behavior, movement, nerve conduction, hormone synthesis and release, blood pressure, and ion fluxes and has been postulated to act as an intrarenal natriuretic hormone.
Multiple D2 dopamine receptors produced by alternative RNA splicing
TLDR
The identification and cloning of a cDNA encoding an RNA splice variant of the rat D2 receptor cDNA is reported, which codes for a receptor isoform which is predominantly expressed in the brain, and contains an additional 29 amino acids in the third cytoplasmic loop, a region believed to be involved in G protein coupling.
Cloning of the gene for a human dopamine D5 receptor with higher affinity for dopamine than D1
TLDR
The cloning of a gene encoding a 477-amino-acid protein with strong homology to the cloned Dt receptor is reported here the existence of a dopamine D1-like receptor with these characteristics had not been predicted and may represent an alternative pathway for dopamine-mediated events and regulation of D2 receptor activity.
Cloning and expression of a rat D2 dopamine receptor cDNA
TLDR
This receptor has been characterized on the basis of three criteria: the deduced amino-acid sequence which reveals that it is a member of the family of G-protein-coupled receptors; the tissue distribution of the mRNA which parallels that of the D2 dopamine receptor; and the pharmacological profile of mouse fibroblast cells transfected with the cDNA.
Alternative splicing directs the expression of two D2 dopamine receptor isoforms
TLDR
It is shown that the gene for the D2 receptor produces two receptor isoforms by alternative messenger RNA splicing, providing a route to receptor diversity in this family of receptors.
Functional coupling of human D2, D3, and D4 dopamine receptors in HEK293 cells.
TLDR
In these cells, activation of D2, D3 or D4 receptors resulted in the inhibition of forskolin-stimulated adenylate cyclase activity in a dose responsive manner, and ribonuclease protection studies demonstrated the presence of D4 dopamine receptor mRNA in human brain regions.
Cloning and expression of human and rat Dt dopamine receptors
TLDR
The cloning of human and rat D1 dopamine receptors by applying an approach based on the polymerase chain reaction is reported, which reveals that it is a G protein-coupled receptor.

TLDR
The results suggest that the two dopamine receptor isoforms are differentially coupled to G proteins, which are mediated by pertussis toxin-sensitive G proteins.
Review: D1 dopamine receptor—the search for a function: A critical evaluation of the D1/D2 dopamine receptor classification and its functional implications
TLDR
A variety of biochemical, behavioral, and electrophysiological evidence is presented which supports the view that D1 and D2 DA receptors can interact in both an opposing and synergistic fashion.
