OpR types are classified according to the ligands which bind to them. The μ-opioid receptor binds morphine. For more details on μ-opioid receptor see Mu Opioid Receptor Bound to a Morphinan Antagonist μ Opioid Receptors Mu Opioid Receptor. 6dde μ-opioid receptor: G protein complex The κ-opioid receptor binds opium-type ligands. For details see Student Project 3 for UMass Chemistry 423 Spring 2015. The δ-opioid receptor binds enkephalins. For details see Delta opioid receptor. The Nociceptin/orphanin FQ opioid receptor binds the heptadecapeptide orphanin[2]. See also Opioids Treatments:Opioid drugs Tutorial: The opioid receptor, a molecular switch Relevance Nociceptin/orphanin FQ opioid receptor plays a role in the regulation of reward and motivation of substance abuse and is a target of drug abuse medication[3]. Its agonists are useful in treatment of pain, anxiety, edema and more and its antagonists are useful in pain management, depression, dementia and Parkinson disease[4]. Structural highlights The has a [5]. . Water molecules are shown as red spheres.
