Frataxin/FXN Protein, Mouse, Recombinant (His)

Promotes the biosynthesis of heme and assembly and repair of iron-sulfur clusters by delivering Fe (2+) to proteins involved in these pathways. May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe (2+) to Fe (3+) ; the oligomeric form but not the monomeric form has in vitro ferroxidase activity. May be able to store large amounts of iron in the form of a ferrihydrite mineral by oligomerization. Modulates the RNA-binding activity of ACO1.
