Three-node motifs and corresponding themes in the integrated S. cerevisiae network. (a) A motif corresponding to the 'feed-forward' theme; (b) motifs corresponding to the 'co-pointing' theme; (c) motifs corresponding to the 'regulonic complex' theme; (d) motifs corresponding to the 'protein complex' theme; (e) motifs corresponding to the theme of neighborhood clustering of the integrated SSL/homology network; (f) motifs corresponding to the 'compensatory complex members' theme; (g) motifs corresponding to the 'compensatory protein and complex/process' theme; (h) other unclassified motifs. Each of (a-g), from left to right, shows a schematic diagram unifying the collection of motifs in that set, the list of motifs with the motif statistics, a specific example of a subgraph matching one or more of these motifs, and a larger structure corresponding to the network theme. Each colored link represents one of the five interaction types according to the color scheme (bottom right). For a given motif, Nreal is the number of corresponding subgraphs in the real network, and Nrand describes the number of corresponding subgraphs in a randomized network, represented by the average and the standard deviation. A node labeled 'etc.' signifies that the structure contains more nodes with connectivity similar to the labeled node.
