Data Sheet
Background: The human dopamine receptor D4 is a D2-like receptor that inhibits adenylyl cyclase activity and activates K+ channels. D4 receptor antagonists show great potential in the treatment of human personality and psychiatric disorders, such as ADHD (Attention deficit hyperactivity disorder), schizophrenia, alcoholism, and drug addiction.
Application: Functional assays
Figure 1. Dose-dependent inhibition of forskolin-stimulated intracellular cAMP level upon treatment with ligand, measured with MultiscreenTM TR-FRET cAMP 1.0 No Wash Assay Kit (Multispan MSCM01). Figure 2. Receptor expression on cell surface measured by flow cytometry (FACS) using an anti-FLAG antibody. Thin line: parental cells; thick line: receptor-expressing cells.
