A heptadecapeptide was identified and purified from porcine brain tissue as a ligand for an orphan heterotrimeric GTP-binding protein (G protein)-coupled receptor (LC132) that is similar in sequence to opioid receptors. This peptide, orphanin FQ, has a primary structure reminiscent

Peptides, 21(7), 949-960 (2000-09-22)
A review of the binding studies performed on the receptor (ORL) for Orphanin FQ/Nociceptin is presented. Binding studies have been conducted using a variety of receptor sources: cell lines expressing the cloned receptor, cell lines endogenously expressing the receptor, and

A novel opioid receptor-like orphan receptor (ORL1) was cloned and identified to be homologous to classical opioid receptors but insensitive to traditional opioids. A heptadecapeptide, termed orphanin FQ or nociceptin (OFQ/N), was identified as its endogenous ligand. OFQ/N shares overlapping
J C Meunier et al.
Nature, 377(6549), 532-535 (1995-10-12)
The ORL1 receptor, an orphan receptor whose human and murine complementary DNAs have recently been characterized, structurally resembles opioid receptors and is negatively coupled with adenylate cyclase. ORL1 transcripts are particularly abundant in the central nervous system. Here we report
