Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Target Background

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.

  1. This study demonstrated that mouse model of Friedreich's ataxia showed that decreased grip strength endurance time , threshold of peripheral sensitivity using Von Frey monofilaments and gait parameters. PMID: 27575947
  2. Here, the authors show that loss of Fxn in the nervous system in mice also activates an iron/sphingolipid/PDK1/Mef2 pathway, indicating that the mechanism is evolutionarily conserved. PMID: 27901468
  3. The in vitro antioxidant treatments trigger the axonal re-growth and the increase in stable MTs in shFxn, thus contributing to identify new neuronal targets of oxidation in this disease and providing a novel approach for antioxidant therapies. PMID: 27516386
  4. Retinal FXN levels are increased in response to ischemia. Furthermore, elevated FXN levels had a clear neuroprotective effect as shown by increased ganglion cell survival after acute retinal ischemia/reperfusion. Frataxin's neuroprotective effect was associated with an upregulation of antioxidative enzymes. PMID: 27537261

  6. Frataxin-deficient mice, which had higher mitochondrial iron loading, showed impaired airway mucociliary clearance and higher pulmonary inflammation at baseline. PMID: 26752519
  7. Using a mouse model of hepatic FXN deficiency in combination with mice deficient for IRP1, a key regulator of cellular iron metabolism, we show that IRP1 activation in conditions of Fe-S deficiency increases the available cytosolic labile iron pool PMID: 25651183
  8. The Fxn KO/Mck mice tested from one to two months of age showed abnormal gait patterns accompanied by a loss in motor skills PMID: 25765157
  9. Reduced expression of frataxin in Friedreich's ataxia leads to elevation of COX2-mediated oxylipin synthesis stimulated by increases in transcription factors that respond to increased reactive oxygen species. PMID: 25104852
  10. Frataxin-deficient cells showed a specific inhibition of mitochondrial Complex I activity already at 70% residual frataxin levels, whereas the glutathione imbalance progressively increased after silencing. PMID: 24714088
  11. The results support a mechanistic hypothesis in which frataxin deficiency decreases Nrf2 expression in vivo, causing the sensitivity to oxidative stress in target tissues the DRG and the cerebella, which contributes to the process of neurodegeneration. PMID: 23350650
  12. rescue of the Friedreich ataxia knockout mutation in transgenic mice containing an FXN-EGFP genomic reporter PMID: 24667739
  13. these results indicate that IGF-I exerts cell-context neuroprotection in frataxin deficiency that maybe therapeutically effective. PMID: 23039828

  21. frataxin may act as a mitochondrial tumor suppressor protein PMID: 16278235
