Overview of pair PSSM for searching homologous protein-protein interactions. For each 3D-dimer with SCOP annotation derived from Protein Data Bank, the pair PSSM is constructed to assess the fit of any possible interacting protein pairs. We use these dimers as queries to search target protein database and identify homologous protein-protein interactions of the query using the pair PSSM.
