Network graph of the statistically significant links between the TAP and HMS complexes and annotated regulons. Each node represents a complex (red ellipse) or a regulon (blue rectangle). Individual complexes are identified by a number, prefixed by TAP  or HMS . Regulons are denoted by the name of the bound transcription factor. The number of genes in each group (complex or regulon) is given in parentheses. The number of genes common to a given complex-regulon pair is indicated along the lines (arcs) joining the pair. (a-g) Seven dense clusters of connections. (h) The set of remaining very small clusters are grouped, each involving mostly one or two connections. Clusters (a-c) are detailed in Figure 4.
