Introduction of OPRL1
Nociceptin receptor (OPRL1) is a protein that in humans is encoded by the OPRL1 gene. OPRL1 is a member of the opioid subfamily of G protein-coupled receptors whose natural ligand is the 17 amino acid neuropeptide and known as nociceptin (N/OFQ). This receptor is involved in the regulation of numerous brain activities, particularly instinctive and emotional behaviors.

|Organism||Homo sapiens (Human)|
Function of OPRL1 Membrane Protein
OPRL1 controls a wide range of biological functions ranging from nociception to food intake, from memory processes to cardiovascular and renal functions, from spontaneous locomotor activity to gastrointestinal motility, from anxiety to the control of neurotransmitter release at peripheral and central sites. The outcome of OPRL1 activation on the brain’s pain circuitry is site-specific. And OPRL1 activation at the spinal cord and peripheral nervous system result in morphine-comparable analgesia in non-human primates. Recent studies indicate that targeting OPRL1 is a promising alternative route to relieving pain without the deleterious side effects of traditional MOP-activating opioid therapies.

Application of OPRL1 Membrane Protein in Literature
The article has demonstrated that OPRL1 modulates a variety of biological functions, ranging from nociception to food intake, from memory processes to cardiovascular and renal functions.
This article suggests that nociceptin (NC) is an endogenous antagonist of dopamine transport and that it affects locomotion and other activities at least partly by inhibiting dopamine transporter and directly affecting dopamine transmission or by inhibiting GABA transporter to indirectly change dopamine transmission.
This article suggests that the aversive effects of stress were mediated by CRF2 receptor stimulation of dynorphin release and subsequent KOR activation.
This article tells us that Salvinorin A is the first naturally occurring nonnitrogenous opioid-receptor subtype-selective agonist.
This article discusses how OPRL1 pharmacology intersects, contrasts, and interacts with the mu opioid receptor in terms of tertiary structure and mechanism of receptor activation.
