D2S Human Dopamine GPCR Binding Agonist Radioligand LeadHunter Assay - FR

Background Information:

Five subtypes of dopamine receptors, D1, D2, D3, D4 and D5, were identified on the basis of pharmacological or biochemical criteria. The D2-like receptors include the two isoforms of the D2 receptor, differing in the length of their predicted third cytoplasmic loop, dubbed D2 short (D2S) and D2 long (D2L). The dopamine D2S receptor couples to PTX-sensitive G proteins (Gi/o) to initiate multiple signaling pathways. In cells of neuroendocrine origin, the D2S couples to "inhibitory" pathways, including inhibition of adenylyl cyclase, activation of potassium channels to hyperpolarize the cell membrane, and inhibition of L-type calcium channels, which in concert mediate inhibition of hormone secretion and gene transcription, and inhibition of cell proliferation. D2 dopamine receptors have been implicated in the pathophysiology of schizophrenia and Parkinson’s disease.
