Figure 4.

Agreement of TP interactor protein normalization versus total number of protein occurrences, by corresponding organism source. This figure shows the total number of interactor proteins in the test set for each organism with respect to the percentage agreement between different participating systems in case of the correct (true positive [TP]) predictions. Each circle represents the interactor protein set for a single species in the test set. Human (red circle), mouse (pink circle), rat (orange circle), and yeast (green circle) proteins are the most frequent interactor protein organism sources in the interaction pair subtask (IPS) test set collection. A total of 50 different organisms were included in the test set (considering the SwissProt subset), corresponding to 1,110 unique interactor proteins.
