About the Program

PSORT is an expert system for the prediction of protein localization sites in cells. It receives the information of an amino acid sequence and its source orgin, e.g., Gram-negative bacteria, as inputs. Then, the system analyzes the input sequence by applying the stored rules for various sequence features of known protein sorting signals. Then, it reports the possiblity for the input protein to be localized at each candidate site with additional information.
