Target Background

G-protein coupled opioid receptor that functions as receptor for the endogenous neuropeptide nociceptin. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Signaling via G proteins mediates inhibition of adenylate cyclase activity and calcium channel activity. Arrestins modulate signaling via G proteins and mediate the activation of alternative signaling pathways that lead to the activation of MAP kinases. Plays a role in modulating nociception and the perception of pain. Plays a role in the regulation of locomotor activity by the neuropeptide nociceptin.

  1. The rs2229205 SNP in the OPRL1 gene may be a genetic factor that contributes to individual differences in the vulnerability to smoking in Japanese individuals PMID: 27490265
  2. The results of in vitro Ala scanning analyses revealed that the labeled residues were Cys59 in TM1, Cys215 and Cys231 in TM5, and Cys310 in TM7.

  7. Data suggest that the nociceptin/nociceptin receptor system is involved in modulation of psychological and inflammatory stress responses and in pathogenesis of anxiety. [REVIEW] PMID: 25677776
  8. Data suggest that interaction between the nociceptin/nociceptin receptor system and the orexin/orexin receptor system in neurons of the hypothalamus positively and negatively modulate complex and integrated responses to stress. [REVIEW] PMID: 25677777
  9. Data suggest that nociceptin/nociceptin receptor signaling in neurons of the hippocampus modulate learning and memory. [REVIEW] PMID: 25677778

  13. Decreased plasma nociceptin/orphanin FQ is closely associated with the presence of acute cardiovascular disease, and the severity of symptoms has a significant negative correlation with the N/OFQ levels. PMID: 22849833
  14. crystal structure of human NOP (also known as ORL-1), solved in complex with the peptide mimetic antagonist compound-24 PMID: 22596163
  15. Our studies reported here show that ORL1 exhibits the ability to cross-desensitize CXCR4 in both primary leukocytes and hematopoetic cell lines PMID: 21656184
  16. The presence of at least one C allele is associated with a decreased expression of OLR1 mRNA in the absence of hsa-miR369-3p de-regulation PMID: 21709374
  17. OPRL1 expression was 1.83 times higher in vitiligo involved skin when compared to healthy control skin. PMID: 20888736
  18. study provides evidence for an association of two variants of the OPRL1 gene, rs6090041 and rs6090043, with vulnerability to develop opiate addiction, suggesting a role for nociceptin/orphanin FQ receptor in the development of opiate addiction PMID: 20032820
  19. Our results support the concept postulating that chronic ethanol consumption and withdrawal downregulate the PNOC/OPRL1 system, which critically controls alcohol intake. PMID: 19501074
  20. Data show that the dynamic cycle between nociceptin receptor activation, internalization and recycling determines the activity of this receptor on the cell surface. PMID: 12568343
  21. Nociceptin receptor mRNA is expressed in human trigeminal ganglia but not in basilar arteries. PMID: 12576178
  22. OP4/ORL1 receptor is synthesized and functionally expressed in vascular endothelial cells, presumably as a starting point for some vasoactive mechanism(s). PMID: 14660000
  23. Nociceptin-induced receptor endocytosis mainly occurred via clathrin-coated pits. Mainly internalized through the endosome compartment. Receptor phosphorylation necessary for internalization. PMID: 15016723
  24. Results suggest that opioid receptor-like (ORL1) receptor utilizes both G(oA) and G(oB) for signal transduction. PMID: 16800795
  25. The ORL-1 receptor is expressed by all subtypes of leukocytes; its function is not the modulation of cytokine production and requires further studies. PMID: 16807742
  26. Polymorphism not associated with panic disorder. PMID: 17167337
  27. molecular analysis of the nociceptin receptor and its ligand complexes PMID: 17456499

Subcellular Location
Cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle. Note=Ligand binding leads to receptor internalization into cytoplasmic vesicles, decreasing the amount of available receptor at the cell surface. Internalization requires phosphorylation at Ser-363. Can recycle to the cell membrane.
Protein Families
G-protein coupled receptor 1 family
Tissue Specificity
Detected in blood leukocytes.
