Fig. 5From: Localization-specific distributions of protein pI in human proteome are governed by local pH and membrane chargeRegression analysis of relationships between protein pI, intra-organelle pH and membrane charge. Spearman’s correlation coefficients and their p-values are indicated in panels a and b. Coefficients of determination for the polynomial (degree 2 and 3), exponential, linear, power, and logarithmic regressions are presented in panels c and dBack to article page
