Nociceptinski receptor (NOP, orfaninski FQ receptor, kapa tip 3 opioidni receptor) je protein koji je kod čoveka kodiran OPRL1 (opioidnom receptoru sličan 1) genom.[1] Nociceptinski receptor je G protein-spregnuti receptor čiji prirodni ligand je poznat kao nociceptin ili orfanin FQ, koji je neuropeptid sa 17 aminokiselina.[2] Ovaj receptor učestvuje u regulaciji brojnih moždanih aktivnosti, posebno instinktivno i emociono ponašanje.[3]
Za nekoliko često korištenih lekova, kao što su etorfin i buprenorfin, je pokazano da se vezuju za nociceptinski receptor, ali da je to vezivanje relativno zanemarljivo u poređenju sa njihovom aktivnošću na drugim opioidnim receptorima. Nedavno je je opseg selektivnih ORL-1 liganda bio razvijen. Oni imaju mali ili nemaju afinitet za druge opioidne receptore, tako da omogućavaju studiranje ORL-1 posredovanih responsa.

Buprenorfin (nije selektivan za ORL-1, parcijalni agonist µ-opioidnog i δ-opioidnog receptora, i kompetitivni antagonist ϰ-opioidnog receptora)
