Abstract Background Large-scale studies have revealed networks of various biological interaction types such as protein-protein interaction genetic interaction transcriptional regulation sequence homology and expression correlation. Recurring patterns of interconnection or network motifs have revealed biological insights for networks containing either one or two types of interaction. Results To study more complex relationships involving multiple biological interaction types we assembled an integrated Saccharomyces cerevisiae network in which nodes represent genes or their protein products and differently colored links represent the aforementioned five biological interaction types. We examined three- and four-node .
