From: Differential evolutionary conservation of motif modes in the yeast protein interaction network
Frequencies of motif topologies and motif modes in the yeast PPI network. Motif counts (in filled triangles and open squares) of eight motif topologies and occurrences (in filled and open circles) of the motif modes of each motif topology on a semi-log plot. If the motifs containing the protein nodes of which the GO annotations are GO:0005554 (function unknown) or have no GO annotation, the motifs were disregarded and plotted in open squares. Occurrences of motif modes are indicated as filled and open circles when the GO terms at depths five and six were employed, respectively.
