Evolution of protein-protein interaction networks in yeast
Fig 4
Comparing the change in protein-protein interaction to protein degree and rate of sequence change across the phylogeny.
Comparison of changes in PPIs across the phylogeny (γ) to degree (A) or to rate of substitution across the phylogeny (ω) (B). A protein’s γ is correlated with its degree in the network (see regression line in panel A), but not with its overall rate of substitution.
