GeneCards Summary for OPRD1 Gene
OPRD1 (Opioid Receptor Delta 1) is a Protein Coding gene. Diseases associated with OPRD1 include Neonatal Abstinence Syndrome and Heroin Dependence. Among its related pathways are Peptide ligand-binding receptors and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and opioid receptor activity. An important paralog of this gene is OPRM1.
UniProtKB/Swiss-Prot for OPRD1 Gene
G-protein coupled receptor that functions as receptor for endogenous enkephalins and for a subset of other opioids. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling leads to the inhibition of adenylate cyclase activity. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Plays a role in the perception of pain and in opiate-mediated analgesia. Plays a role in developing analgesic tolerance to morphine.
The delta opioid receptor (also known as OP1, DOP, DOR) is a member of the opioid family of G-protein-coupled receptors that also includes mu, kappa and NOP receptors. In the CNS, delta opioid receptors are primarily distributed in the olfactory bulb, nucleus accumbens and neocortex.
