Dopamine receptors belong to the rhodopsin like family of G-protein coupled receptors (GPCRs). There are five subtypes of DA receptors (D1-D5), which are

Dopamine is monoamine neurotransmitter. Dopamine is produced in the dopaminergic neurons in the ventral tegmental area of the substantia nigra, midbrain and the arcuate nucleus of the hypothalamus.

Abnormalities in dopamine receptor signaling may lead to neuropsychiatric disorders such as Parkinson's disease and schizophrenia. Dopamine receptors http://truthofaddiction.com Click Link for more information. Featured in Science Daily, the first direct evidence shows us that dopamine Dopamine receptors have different molecular features and functions depending on their anatomical location within the striatum. The findings could help develop better-targeted treatments for a range of disorders from schizophrenia to Parkinson's disease.

Stimulation of dopamine receptors modulates natriuresis in the kidney and cell division and hormone synthesis and secretion in the pituitary. dopamine receptors in the mesocortical pathway [10,12,13]. The Tuberoinfundibular Pathway which originates in the arcuate nucleus ofthe hypothalamus (arcuate and paraventricular nuclei) Dopamine receptor D2, also known as D2R, is a protein that, in humans, is encoded by the DRD2 gene.

Volkow.

Location of D3,D4,D5: These are primarily present in brain. D4 receptors are expressed in atrial wall. dopamine increases myocardium contractility. Dopamine released from the hypothalamus controls the synthesis and secretion of prolactin from the anterior pituitary via D2 dopamine receptors. As yet none of the dopamine receptor subtypes have been associated with the etiology of psychotic disorders, such as schizophrenia. The D1 receptor is the most abundant dopamine receptor in the brain.

The actions of dopamine receptors, by themselves, and by counterbalancing the prohypertensive effects of the α-adrenergic nervous system and RAS, keep the blood pressure in the normal range. The dopamine receptor subtypes are divided into two major subclasses: types 1 and 5 are similar in structure and drug sensitivity, and these two receptors are referred to as the "D1like" group or D 1 receptor has a high degree of structural homology to another dopamine receptor, D 5, and they both bind similar drugs. As a result, none of the known orthosteric ligands is selective for the D 1 vs.
