Opioid receptors are a group of G protein-coupled receptors with opioids as ligands. The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin. The opioid receptors are approximately 40% identical to somatostatin receptors. Opiate receptors are distributed widely in the brain, and are found in the spinal cord and digestive tract.
