Many protein families contain homologous proteins that have a common biological function but different specificity. Given a multiple sequence alignment of a family divided into specificity groups, SDPpred predicts a set of alignment positions (SDP, Specificity-Determining Positions) that determine differences in the functional specificity. If analysing transmembrane proteins, there is a possibility to predict TM segments first, and then use special matrices for TM segments in the analysis. Additional feature is SDP-profile based prediction of specificity.
