Karlin's predicted gene expression and measured protein abundance. The dotted line is linear regression and the solid line a loess local fitting curve. The Pearson correlation coefficient between log(copy number) and Karlin's expression value is 0.52 (p-value < 10-12) and the Spearman's rho is 0.53 (p-value < 10-12).
