Dopamine receptors are G protein-coupled integral membrane receptors. They have crucial modulator roles in motor activities, motivation, drive, and cognition, and are widely dispersed throughout the brain. There are five distinct types of dopamine receptors, designated D1, D2, D3, D4, and D5. The different receptors throughout the body provide unique functions. Many neuropsychiatric disorders, such as schizophrenia, bipolar disorder, depression, and Parkinson's disease, respond well to drugs that target dopamine receptors. Thus, drug development in neuropsychiatric disorders may benefit from a more detailed understanding of dopamine receptor function.

To help in determining the role of dopamine receptors, Creative Biolabs, a forerunner in the study of GPCR function, offers a fast and robust Magic™ in vitro cell-based dopamine receptor functional assay service.
Different dopamine receptors activate different signaling pathways. They activate the G proteins coupled to receptors and trigger the different downstream signaling pathways. Based on this fact, our Magic™ in vitro cell-based dopamine receptor functional assay service is carried out by measuring the cAMP concentration and ion flow to assay compounds, as well as analyzing their capability to modulate dopamine receptors and signaling pathways. We leverage our extensive professional expertise and project experience to help customers:

Summary: The primary goals of this research were to identify the potential mechanisms of action of fucoxanthin and fucosterol through in silico molecular docking studies and to characterize the role of fucoxanthin and fucosterol in the aminergic pathway via in vitro human monoamine oxidase (hMAO) inhibition and cell-based functional G-protein coupled receptor (GPCR) assays. The results demonstrate that fucoxanthin acts as an agonist at dopamine D3 and D4 receptors, with the strength of this effect being dose-dependent.

Q1: What transpires when blocking dopamine receptors?
A1: Parakineis, dystonia, tics, tremors, oculomotor movements, orolingual and other dyskinesias, and akathisia have all been linked to dopamine receptor-blocking medications in children and adolescents. Anytime after starting therapy, symptoms are possible.
Q2: Can ELISA detect receptors?
A2: The enzyme-linked immunoabsorbant assay (ELISA) has many benefits for identifying and measuring cell surface receptors. The current cell surface ELISA methods allow for unambiguous evaluation of receptors located specifically on the plasma membrane.
