Mitochondrial Ca 2+ handling plays an important role in energy production and various cellular signaling processes. Mitochondrial Ca 2+ uptake is regulated by the mitochondrial Ca 2+ uniporter (MCU), at least one non‐MCU Ca 2+ channel and possibly a mitochondrial ryanodine receptor. Two distinct mechanisms mediate Ca 2+ outward transport, the Na + ‐dependent (mNCX) and the Na + ‐independent Ca 2+ efflux. In recent years we gained more insight into the regulation and function of these different Ca 2+ transport mechanisms. However, the precise physiological role and the molecular structure of all mitochondrial Ca 2+ transporters and channels still has to be determined.
