From: The role of exon shuffling in shaping protein-protein interaction networks
Influence of shuffling upon presence in the human PPI network (A) Percentage of protein-coding genes in the human PPI network according to shuffling profile category. Numbers above bars indicate the absolute number of genes in the network, and the total number of protein-coding genes of the species. (B) Chi-square values and p-values for comparisons among groups in Panel A concerning presence in PPI networks.
