Frataxin is a protein that in humans is encoded by the FXN gene.
Frataxin is a protein that in humans is encoded by the FXN gene.
It is located in the mitochondrion and frataxin mRNA is mostly expressed in tissues with a high metabolic rate. The function of frataxin is not clear but it is involved in assembly of iron-sulfur clusters. It has been proposed to act as either an iron chaperone or an iron storage protein. Reduced expression of frataxin is the cause of Friedreich's ataxia.
