CC   -!- FUNCTION: [Nociceptin]: Ligand of the opioid receptor-like receptor
CC       OPRL1. It may act as a transmitter in the brain by modulating
CC       nociceptive and locomotor behavior. May be involved in neuronal
CC       differentiation and development. {ECO:0000269|PubMed:7566152}.
CC   -!- FUNCTION: [Nocistatin]: Blocks nociceptin action in pain transmission
CC       by inhibiting nociceptin-induced hyperalgesia and allodynia.
CC       {ECO:0000250|UniProtKB:O62647}.
CC   -!- FUNCTION: [Orphanin FQ2]: Has potent analgesic activity.
CC       {ECO:0000250|UniProtKB:Q64387}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed predominantly in the spinal cord and
CC       brain, being more abundant in the hypothalamus and striatum. Also found
CC       in small amounts in ovary. {ECO:0000269|PubMed:8710928,
CC       ECO:0000269|PubMed:8710930}.
CC   -!- PTM: Specific enzymatic cleavages at paired basic residues probably
CC       yield other active peptides besides nociceptin.
CC   -!- PTM: The N-terminal domain contains 6 conserved cysteines thought to be
CC       involved in disulfide bonding and/or processing.
CC   -!- SIMILARITY: Belongs to the opioid neuropeptide precursor family.
CC       {ECO:0000305}.
