WebMar 30, 2024 · Morphine is an opioid pain reliever (analgesic) used to manage moderate-to-severe acute and chronic pain, including post-surgical pain, and pain caused by cancer … An additional opioid receptor was later identified and cloned based on homology with the cDNA. This receptor is known as the nociceptin receptor or ORL1 (opiate receptor-like 1). The opioid receptor types are nearly 70% identical, with the differences located at the N and C termini. The μ receptor is … See more Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands. The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin.
