prokineticin-2β   Click here for help

GtoPdb Ligand ID: 1868

Abbreviated name: PK2β
Compound class: Endogenous peptide in human, mouse or rat
Comment: Prokineticin-2β is 21 amino acids shorter than the parent peptide. This shorter variant is believed to arise as the result of post-translational protein cleavage events. Prokineticin-2β has been identified in human, rat and mouse [1].
Species: Human

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.
