Orphanin FQ / Nociceptin — frequently asked
What is orphanin FQ / nociceptin?
It is a seventeen-residue peptide identified as the endogenous ligand of the NOP receptor, previously called ORL1. Two research groups described it at almost the same time, which is why the peptide carries two widely used names.
Is it an opioid peptide?
It belongs to the opioid peptide structural family and its receptor is opioid-like, but reports indicate very low affinity for classical mu, delta and kappa receptors. It is therefore usually treated as a separate non-opioid branch of that system.
What other peptides come from the same precursor?
Prepronociceptin is described as yielding nocistatin and nociceptin-related sequences such as OFQ2 in addition to the parent peptide. These fragments are often studied together, since some reports describe opposing actions between nocistatin and nociceptin.
