Mitochondria are the main source of energy in eukaryotic cells, oxidizing sugars and fats to generate ATP through oxidative phosphorylation (OXPHOS), which is accomplished by the respiratory chain (Figure 1). Defects in OXPHOS affect the respiratory chain and lead to classical childhood mitochondrial disease, which has an incidence of at least ~1/5000 live births. Organs with the highest energy demand such as brain and heart are normally affected, although the disease can affect any organ system alone or in combination. Mutations in almost 200 genes cause mitochondrial disease.
Diagnostic approaches typically focus on known mitochondrial disease genes, whereas the genetic complexity of the disease means drugs targeting one OXPHOS system often fail when another is defective. Functionalisation of the mitochondrial proteome is therefore crucial for improving diagnostic and treatment outcomes.
To functionalise the mitochondrial proteome we apply cutting-edge systems biology approaches, incorporating extensive gene-editing and proteomics tools, as well as classical biochemical, molecular and cell biology techniques.
