Table 1 Data sets. The characteristics of protein interaction data sets for yeast, worm, fruitfly and humans, the corresponding-domain information, and the values of fn and fp used in the analysis. Only protein pairs with both proteins containing Pfam-A domains are included in the protein interaction data sets, and proteins in those protein interactions are counted. The numbers in the parenthesis are the total number of available protein interactions.
