Abstract

The Mitochondrial Proteome: from inventory to function

Mitochondria are cellular powerhouses, synthesizing the bulk of the ATP used by eukaryotic cells. The cellular function of mitochondria, however, is not limited to bioenergetics. They play crucial roles in the metabolism of amino acids and lipids, the biosynthesis of heme and iron-sulfur clusters, cell signaling, and apoptosis. Mitochondrial proteins are encoded by two genomes. In humans, the mitochondrial genome codes for only 13 proteins; the remaining 99% of mitochondrial proteins are encoded by nuclear genes and are synthesized as precursors on cytosolic ribosomes and then are imported into mitochondria. To understand the role of mitochondria in health and disease, it is important to know the protein composition of this organelle.
