We note that a set of statistically "unusual" protein-profilepairs in experimentally determined database ofprotein-protein interactions can typify protein-proteininteractions, and propose a novel method calledPICUPP that sifts such protein-profile pairs using astatistical simulation. It is demonstrated that unusualPfam and InterPro profile pairs can be extracted fromthe DIP database using a bootstrapping approach. Weparticularly illustrate that such protein-profile pairs canbe used for predicting putative pairs of interactingproteins. Their prediction accuracies are around 86%and 90% when InterPro and Pfam profiles are used,respectively at 75% confidence level.
