Figure 4From: An exploration of alternative visualisations of the basic helix-loop-helix protein interaction networkPhylogenetic interaction matrix for the bHLH PPI network. The inferred bHLH phylogenetic tree from [11] is shown on the left (branch lengths are not to scale). Intra-sub-family interactions are shown in the matrix to the right as filled cells in the same sub-family colour designations as figure 1; interactions between sub-families are in grey.Back to article page
