  2. Opioid receptor - Wikipedia

    en.wikipedia.org/wiki/Opioid_receptor

    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 perhaps the most important.

  3. μ-opioid receptor - Wikipedia

    en.wikipedia.org/wiki/Μ-opioid_receptor

    The μ-opioid receptors (MOR) are a class of opioid receptors with a high affinity for enkephalins and beta-endorphin, but a low affinity for dynorphins. They are also referred to as μ( mu )-opioid peptide (MOP) receptors.

  4. κ-opioid receptor - Wikipedia

    en.wikipedia.org/wiki/Κ-opioid_receptor

    The κ-opioid receptor or kappa opioid receptor, abbreviated KOR or KOP for its ligand ketazocine, is a G protein-coupled receptor that in humans is encoded by the OPRK1 gene. The KOR is coupled to the G protein G i /G 0 and is one of four related receptors that bind opioid -like compounds in the brain and are responsible for mediating the ...

  5. Opioid - Wikipedia

    en.wikipedia.org/wiki/Opioid

    By the late 1960s, research found that opiate effects are mediated by activation of specific molecular receptors in the nervous system, which were termed "opioid receptors". [250] The definition of "opioid" was later refined to refer to substances that have morphine-like activities that are mediated by the activation of opioid receptors.

  6. Opioid peptide - Wikipedia

    en.wikipedia.org/wiki/Opioid_peptide

    Opioid peptides or opiate peptides are peptides that bind to opioid receptors in the brain; opiates and opioids mimic the effect of these peptides. Such peptides may be produced by the body itself, for example endorphins .

  8. Opiate - Wikipedia

    en.wikipedia.org/wiki/Opiate

    Opioids act upon opioid receptors that are coupled to inhibitor G protein coupled receptors (GPCR). These receptors fall into 3 classes: μ (mu), δ (delta), and κ (kappa) receptors. [36] More than 70% of opioid receptors are μ receptors, predominantly located on the central terminals of nociceptors in the dorsal horn of the spinal cord.
