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.

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 ...
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.
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.
β-Endorphin is an agonist of the opioid receptors; it preferentially binds to the μ-opioid receptor. [1] Evidence suggests that it serves as a primary endogenous ligand for the μ-opioid receptor , [ 1 ] [ 10 ] the same receptor to which the chemicals extracted from opium , such as morphine , derive their analgesic properties. β-Endorphin ...
Morphine is a phenanthrene opioid receptor agonist – its main effect is binding to and activating the μ-opioid receptor (MOR) in the central nervous system. Its intrinsic activity at the MOR is heavily dependent on the assay and tissue being tested; in some situations it is a full agonist while in others it can be a partial agonist or even ...
Although KOR is the primary receptor for all dynorphins, the peptides do have some affinity for the μ-opioid receptor (MOR), δ-opioid receptor (DOR), and the N-methyl-D-aspartic acid -type glutamate receptor. [6] [8] Different dynorphins show different receptor selectivities and potencies at receptors. Big dynorphin and dynorphin A have the ...
