PeptideLocator is for users interested in identifying bioactive peptides within a protein sequence. PeptideLocator was trained on a set of non-redundant protein sequences conatining known bioactive peptides.


This tool takes a UniProt sequence ID. The method uses the entire protein sequence as input, since it is trained on full length protein sequences. The maximum length of a protein sequence to be analysed is 10,000 residues.


The tool outputs a plot of the PeptideLocator score for each residue in the input protein sequence. This score represents the tool's prediction of the likelihood that each residue is part of a bioactive peptide within that protein sequence. Information about the Relative Local Conservation and the disorder context of the protein are included in the results.
