Synonyms: Gln-Arg-Phe-Ser-Arg | L-Glutaminyl-L-arginyl-L-phenylalanyl-L-seryl-L-arginine | QRFSR peptide
Compound class: Peptide or derivative
Comment: Opiorphin is an endogenous pentapeptide. It reduces the breakdown of the natural analgesic enkephalins by acting as an inhibitor of enkephalin-degrading proteases including neutral ecto-endopeptidase (MME; neprilysin), ecto-aminopeptidase N (ANPEP; ANP)  and dipeptidyl peptidase DPP3.
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖
