From: Reuse of structural domain–domain interactions in protein networks
Venn diagramm showing the fractions of iPfam domain pairs found in the E. coli, S. cerevisiae and H. sapiens binary protein interaction sets. The three circles represent the i Pfam domain pairs observed in the respective species. The overlaps denote co-observed i Pfam domain pairs. The grey set in the background represents i Pfam domain pairs not found in the three species.
