Friedreich's ataxia (FRDA) is a neurological disease related to a deficiency of the protein frataxin involved in iron-sulfur (Fe-S) cluster biogenesis. This leads to an increased cellular iron uptake accumulating in mitochondria, and a subsequently disturbed iron homeostasis. The detailed mechanism of iron regulation of frataxin expression is yet unknown. ...
