Download our Frataxin Brochure. Solutions for monitoring Friedreich's ataxia patients or cell models, inlcuding measurement of frataxin levels and downstream effects of frataxin dysregulation.


UniProt Number: Q16595
Alternate Names: Friedreich ataxia protein, FXN, FRDA, X25, Cleaved into the following 3 chains: Frataxin intermediate form, Frataxin(56-210), Frataxin(81-210)
Structure and Function: Frataxin is a 17 kDa nuclear-encoded mitochondrial protein. In humans the gene is localized on chromosome 9 and is highly conserved during evolution. The gene is expressed in every cell, although in varying levels in different tissues and during development.

The specific function of frataxin is still unknown, but it has been shown to play a role in iron metabolism. Studies have demonstrated that the deletion of the frataxin gene in yeast results in iron accumulation in mitochondria and loss of respiration. Recombinant human frataxin has been shown to bind iron in vitro, and increased mitochondrial iron levels have been observed in patients with Friedreich's Ataxia (FRDA).
Disease Associations: Defects in FXN are the cause of Friedreich ataxia (FA) [MIM:229300]. FA is an autosomal recessive, progressive degenerative disease characterized by neurodegeneration and cardiomyopathy it is the most common inherited ataxia.
