The neuromedin U receptors are two G-protein coupled receptors which bind the neuropeptide hormones neuromedin U and neuromedin S.^[1] There are two subtypes of the neuromedin U receptor, each encoded by a separate gene (NMUR1, NMUR2).

Selective Ligands

Neuromedin U is an agonist at both the NMU₁ and NMU₂ subtypes, while neuromedin S is selective for NMU₂, and is a more potent agonist at this subtype than neuromedin U.^[2][3] Several other peptide and non-peptide ligands are also available for the NMU receptors.

Agonists

Non-selective

• Neuromedin U
• non-peptide NMU modulators ^[4][5]

NMU₂ selective

• Neuromedin S

Antagonists

NMU₂ selective

• R-PSOP ^[6]
