Nociceptin
Nociceptin/Orphanin FQ (N/OFQ)
An endogenous ligand for the NOP receptor (opioid-like receptor). Has complex effects on pain, anxiety, stress, and reward that are distinct from classical opioids.
Mechanism of Action
Nociceptin binds to NOP receptors, modulating pain (pro- or anti-nociceptive depending on context), reducing anxiety, and modulating stress responses. It also affects learning and memory.
