Peptide Ranker


PeptideRanker is a server for the prediction of bioactive peptides based on a novel N-to-1 neural network (described here). PeptideRanker aims to determine for a set of peptides the likelihood that they are bioactive. The peptides can simply be entered into the text box, and will be ranked according to the algorithm's belief that they resemble a bioactive peptide. It does not break down the sequence to look for subsequences within the peptide.


A list of peptide sequences that the user wants to determine whether or not they are bioactive.


A ranked list of the input peptides, scored by PeptideRanker. The score is not a prediction of the degree of bioactivity but a prediction of how likely the peptide is to be bioactive.
