General description
Endomorphin 2 is an endogenous ligand for μ-opioid receptor (MOR). It is a neuropeptide and has the sequence Tyr-Pro-Phe-Phe-NH2. It has a greater affinity for MOR1 receptor than MOR2. It resides in primary sensory afferent fibers, and might be the predominant ligand to regulate pain perception. In dynorphin-induced allodynia mice models, endomorphin has anti-allodynic effects. In tail flick test, it produces short-lived antinociception, which is naloxone-sensitive.
Biochem/physiol Actions
Potent, selective endogenous μ opioid receptor agonist.

Endogenous mu-opioid receptor (MOR) selective peptides, endomorphin-1 (EM-1) and endomorphin-2 (EM-2), unlike so called 'typical opioids', are characterized by the presence of Pro(2) residue, which is a spacer connecting aromatic pharmacophoric residues. In order to investigate structural requirements for position

The recently isolated peptides endomorphin-1 and endomorphin-2 have been suggested to be the endogenous ligands for the mu receptor. In traditional opioid receptor binding assays in mouse brain homogenates, both endomorphin-1 and endomorphin-2 competed both mu1 and mu2 receptor sites
