SignalP - 4.1

Signal peptide and cleavage sites in gram+, gram- and eukaryotic amino acid sequences

SignalP 4.1 server predicts the presence and location of signal peptide cleavage sites in amino acid sequences from different organisms: Gram-positive prokaryotes, Gram-negative prokaryotes, and eukaryotes. The method incorporates a prediction of cleavage sites and a signal peptide/non-signal peptide prediction based on a combination of several artificial neural networks.

NEW (August 2017): A book chapter on SignalP 4.1 has been published:

NOTE (added May 2018): Remember, the presence or absence of a signal peptide is not the whole story about the localization of a protein!
If you want to find out more about the sorting of your eukaryotic proteins, try the protein subcellular localization predictor DeepLoc.
