The functionality of the mitochondrion is primarily determined by nuclear encoded proteins.
The mitochondrial functional requirements of different tissues vary from a significant
biosynthetic role (liver) to a primarily energy metabolism-oriented organelle (heart). The
purpose of this study was to compare the mitochondrial proteome from four different tissues
of the rat, brain, liver, heart, and kidney, to provide insight into the extent of mitochondrial
heterogeneity and to further characterize the overall mitochondrial proteome. Mitochondria …
