Comments
  • FUNCTION: Nociceptin is the ligand of the opioid receptor-like receptor (OPRL1). It may act as a transmitter in the brain by modulating nociceptive and locomotor behavior. May be involved in neuronal differentiation and development.
  • SUBCELLULAR LOCATION: Secreted.
  • TISSUE SPECIFICITY: Expressed predominantly in the spinal cord and brain, being more abundant in the hypothalamus and striatum. Also found in small amounts in ovary.
  • PTM: Specific enzymatic cleavages at paired basic residues probably yield other active peptides besides nociceptin.
  • PTM: The N-terminal domain contains 6 conserved cysteines thought to be involved in disulfide bonding and/or processing.
  • SIMILARITY: Belongs to the opioid neuropeptide precursor family.
