Opioid Peptide

Home » Catalog Peptides » Opioid Peptides

Opioid peptides are released by post-translational proteolytic cleavage of precursor proteins. These peptides can bind to opioid receptors in the brain. Although these effect vary in different peptides, they all resemble those of opiates.

Opioid peptids act as neuromodulators in the body, in order to modify the other neurotransmitters in the central nervous system. These peptides can alter the electrical properties of target neurons, then make neurons more difficult to excite, and finally influence the release of various neurotransmitters.
