Figure 2From: Apparent dependence of protein evolutionary rate on number of interactions is linked to biases in protein–protein interactions data setsThe correlation between evolutionary rate and the number of interactions is directly related to the bias towards counting more interactions for abundant proteins, both when abundance is measured by (A) gene microarray expression levels and (B) CAI. Correlations are Kendall's rank correlation τ, and points are for all data sets listed in Table 1.Back to article page
