[The discovery of a novel opioid-receptor-like receptor and its endogenous ligand].
A novel member of the opioid receptor family (orphan ORL receptor) was cloned in 1994, followed by the discovery of its endogenous ligand OFQ or nociceptin in 1995. ORL receptor has 50% homology with conventional opioid receptor, and OFQ is structurally homologous with dynorphin A. Whether the two systems are functionally antagonistic or synergistic with each other is a subject of future research.
