From: Reuse of structural domain–domain interactions in protein networks
Comparison of coverage of iPfam domain pairs on protein interactions. For each species, the height of the column reflects the number of known protein–protein interactions in the data set. The columns are split according to the proportion of interactions that contain an i Pfam domain pair (blue), that contain any other Pfam domains on both proteins (red), and those that contain no Pfam domain pair (yellow).
