Figure 2. Dual localized proteins of the mitochondrial reference set are enriched for proteins with a low total net charge.
Total Differences in the distribution of total net charge in dual localized (grey) and exclusively mitochondrial (white) proteins were analyzed using χ2 test (p-value <0.001). Statistically significant differences in specific categories according to the χ2 test (df = 1) are marked with asterisks (* p-value <0.05). Mitochondrial localization was determined according to the Mitop2 reference set.
