From: An evolutionary and functional assessment of regulatory network motifs
Motif occurrence in yeast. The network graph of the occurrences of motifs for S. cerevisiae illustrates the fact that most of the motifs are not found in isolation and are part of larger aggregates. Green, pure transcriptional regulation of the target gene by the regulatory gene product protein; red, transcriptional regulation and protein-protein interaction of the two partners; dashed line, pure protein-protein interaction. The pathways that will be examined in detail are shaded.
