Figure 4: Characterization of the interactability of prostate cancer-related proteins from the extended KEGG dataset based on the results of their analysis by APID server. (a) Correlation between the number of PPIs found by APID for individual proteins and protein length. Note logarithmic scale of this plot. (b) Correlation between interactability (evaluated as the number of PPIs per 100 residues of a given protein) and intrinsic disorder (measured as PONDR FIT-based content of predicted disordered residues in a query protein). Note semi-logarithmic scale of this plot.
