Fig. 1

Spearman’s rank correlation between all variable pairs, excluding dN/dS. Edges represent correlation coefficients (ρ) between two properties. All correlations were calculated in the dataset of 1557 proteins, apart from those involving essentiality, which are calculated for 681 proteins. Only correlations significant with p < 0.05 are depicted. See legend of Table 1 for descriptions of the biological variables: 3′UTR, 5′UTR, age, essentiality, ex.lev., multi, para, PPI, CDS, intron, and τ
