Human proteome quantifications across distinct database resources. PaxDb quantifications are compared to Human Protein Atlas and GTEx data. A, Spearman’s correlation between PaxDb abundances and GTEx protein abundances, shown for two example tissues: cerebral cortex and skin. B, Pearson’s correlation for tissue specific abundances in PaxDb against GTEx protein with clustering dendrogram, with PaxDb tissues marked with “P” and GTEx tissues with “G.” C, significance of abundance separation by HPA group label, per human tissue type. D, two examples of protein abundance distributions stratified by HPA categories (liver and gallbladder), showcasing the highest and lowest ANOVA p-values as depicted in C. GTEx, Genotype-Tissue Expression; HPA, Human Protein Atlas; PaxDb, “Protein Abundances Across Organisms” database.
