Opioid Receptor #
- Main subtypes:
- μ-Opioid Receptor (1-3) (Gi)
- κ-Opioid Receptor (1-3) (Gi)
- δ-Opioid Receptor (1-2) (Gi)
- Nociceptin Receptor (ORL)
- Wikipedia calls this kappa type-3. But the kappa page does not acknowledge this.
- Far less known is the ζ-opioid receptor which does much different things.
- µ-receptors mediate many neuroendocrine functions, whereas δ-receptors prevail in peripheral tissue, particularly gastro-intestinal mucosa and intestine.
