Function

   Report protein signal cleavage sites

Description

   SignalP 3.0 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 and hidden Markov models.
