WebSignalP 4.0 shows better discrimination between signal peptides and transmembrane regions, and consequently achieves the best signal sequence prediction. On the other hand, there is still room for improvement on the cleavage site prediction: Precision and sensitivity of current methods hovers around ~66% and ~68%, respectively. WebThe best program for predicting signal sequences was found to be SignalP 2.0-NN with an accuracy of 78.1% for cleavage site recognition. The new data set can be utilized for refining prediction algorithms, and we have built an improved version of profile hidden Markov model for signal peptides based on the new data.
