Mitochondria play a central role in energy metabolism and cellular survival, and consequently mitochondrial dysfunction is associated with a number of human pathologies, such as type 2 diabetes. There is an increasing understanding/interest of the use of reversible protein phosphorylation as a central mechanism in regulating various mitochondrial processes. E.g. in skeletal muscle, aberrant phosphorylation of mitochondrial proteins has been hypothesized to play a role for the link between mitochondrial dysfunction and insulin resistance in humans with obesity and type 2 diabetes. This review summarizes previous studies on the role of protein phosphorylation in mitochondrial functions, mass spectrometry-based phosphoproteomics strategies and phosphoproteomic studies of mitchondria.
