Abstract: International audience; Human mitoNEET (mNT) is the first identified Fe−S protein of the mammalian outer mitochondrial membrane. Recently, we demonstrated the involvement of mNT in a specific cytosolic pathway dedicated to the reactivation of oxidatively damaged cytosolic aconitase by cluster transfer. In vitro studies using apo-ferredoxin (FDX) reveal that mNT uses an Fe-based redox switch mechanism to regulate the transfer of its cluster. Using the "gold standard" cluster recipient protein, FDX, we show that this transfer is direct and that...
