Figure 1. Dual localized proteins of the mitochondrial reference set are enriched for proteins with a low MitoProtII score.

Distribution of MitoProtII scores in dual localized (grey) and exclusive mitochondrial (white) proteins were analyzed using χ² test. Statistically significant differences in specific categories according to the χ² test (df = 1) are marked with asterisks (* p-value <0.05; ** p-value <0.005; *** p-value <0.001). Mitochondrial localization was determined according to the Mitop2 reference set.
