Figure 2From: PCDq: human protein complex database with quality index which summarizes different levels of evidences of protein complexes predicted from H-Invitational protein-protein interactions integrative datasetOverlap of human PPIs in six PPI databases. (a) Pairwise overlaps of PPIs across databases are shown in cells. The number of nonredundant PPIs is shown in parentheses for each database. (b) Overlaps of PPIs shared in common in one, two, three, four, five, and six databases are shown.Back to article page
