[HMDB] D018377 - Neurotransmitter Agents > D004723 - Endorphins Morphiceptin is a peptide isolated from beta-casein. Morphiceptin is a potent and specific agonist for morphine (μ) receptors. Morphiceptin, as a synthetic peptide, is the amide of a fragment of the milk protein β-casein. Morphiceptin has morphinelike activities and is highly specific for morphine (μ) receptors but not for enkephalin (?) receptors[1].
