Sequential forward and reverse transport of the Na+ Ca2+ exchanger generates Ca2+ oscillations within mitochondria
Mitochondrial Ca2+ homoeostasis is tightly regulated and export of Ca2+ is mediated by an Na+Ca2+ exchanger. Here authors show that in depolarised mitochondria the exchanger initially operates in reverse mode, transporting cytosolic Ca2+ into the matrix before it reverts to its forward mode state.
