Nociceptin receptor

Nociceptin receptor, also known as ORL1, is a protein that in humans is encoded by the OPRL1 gene. It is a member of the opioid family of G-protein-coupled receptors. The nociceptin receptor is widely distributed in the central nervous system where it plays a role in pain and stress responses, as well as in the regulation of food intake.

Function[edit | edit source]

The nociceptin receptor is a G protein-coupled receptor that binds the peptide nociceptin. Nociceptin and its receptor system are involved in numerous biological functions, including pain, stress, and anxiety responses, as well as drug abuse and reward. The nociceptin receptor system is also involved in the regulation of locomotor activity and cognitive processes.

Clinical significance[edit | edit source]

Alterations in the nociceptin receptor system have been implicated in a variety of disorders, including chronic pain, anxiety disorders, depression, and drug addiction. As such, the nociceptin receptor represents a promising target for the development of novel therapeutics for these conditions.

Pharmacology[edit | edit source]

Several synthetic ligands for the nociceptin receptor have been developed, including agonists, antagonists, and partial agonists. These compounds have been used to investigate the role of the nociceptin receptor system in various physiological and pathological processes.
