The gene represented in this entry may be involved in disease pathogenesis. DRD2 mutations in myoclonic dystonia patients are rare, and their contribution to disease phenotype is unclear (PubMed:10716258). Function C562_ECOLX Electron-transport protein of unknown function.DRD2_HUMAN Dopamine receptor whose activity is mediated by G proteins which inhibit adenylyl cyclase (By similarity). Publication Abstract from PubMed The D1- and D2-dopamine receptors (D1R and D2R), which signal through G(s) and G(i), respectively, represent the principal stimulatory and inhibitory dopamine receptors in the central nervous system. D1R and D2R also represent the main therapeutic targets for Parkinson's disease, schizophrenia, and many other neuropsychiatric disorders, and insight into their signaling is essential for understanding both therapeutic and side effects of dopaminergic drugs. Here, we report four cryoelectron microscopy (cryo-EM) structures of D1R-G(s) and D2R-G(i) signaling complexes with selective and non-selective dopamine agonists, including two currently used anti-Parkinson's disease drugs, apomorphine and bromocriptine. These structures, together with mutagenesis studies, reveal the conserved binding mode of dopamine agonists, the unique pocket topology underlying ligand selectivity, the conformational changes in receptor activation, and potential structural determinants for G protein-coupling selectivity. These results provide both a molecular understanding of dopamine signaling and multiple structural templates for drug design targeting the dopaminergic system.
