Description générale
Frataxin is a monomeric mitochondrial protein that is believed to be involved in iron homeostasis through an unknown mechanism. Expression of frataxin is highest in tissue rich with mitochondria including liver, heart, and skeletal muscle (Campuzano, 1996; Koutnikova, 1997). Frataxin is expressed as a 30 kDa precursor (transient; 210 amino acids) that is processed within in the mitochondria in two steps catalysed by the mitochondrial processing peptidase (MPP) to yield the mature protein (Koutnikova, 1998). The first step involves cleavage of the first 41 N-terminal amino acids by MPP yielding a transient intermediate of approximately 20 kDa (aa 42-210). Further cleavage of the N-terminus of this 20 kDa intermediate by MPP results in the mature 18 kDa frataxin protein (aa 56-210). Defects in the gene encoding frataxin are implicated as the cause of Friedreich′s ataxia, an autosomal recessive, progressive degenerative disease characterized by neurodegeneration and cardiomyopathy. In the majority of cases of Friedreich′s ataxia, there is an expansion of a trinucleotide repeat in the first intron of the gene encoding frataxin resulting in a marked decrease in frataxin expression, perhaps due to the formation of some unusual yet stable DNA structure that interferes with transcription (Campuzano, 1997; Bidichandani, 1998). This reduction in frataxin expression results in the accumulation of unchelated iron in the mitochondria, inhibition of mitochondrial iron-sulfer proteins, and iron mediated oxidative stress (Foury, 1997; for review see Puccio, 2000).
Spécificité
Expected to cross-react with human.
Human Frataxin. MAB1594 recognizes only isoforms of frataxin containing exon 4. On Western blots of normal human muscle, heart, cerebellum, and spinal cord extracts, MAB1594 recognizes a band migrating at approximately 18 kDa corresponding to processed frataxin (Campuzano, 1997). Slight cross reactivity with myosin may be observed by Western blot. Immunofluorescent labeling of HeLa cells with MAB1594 demonstrates that frataxin is predominantly localized in the mitochondria (Campuzano, 1997).
Immunogène
Epitope: exon 4
Full length human Frataxin fused to TrpE.
Application
Detect Frataxin using this Anti-Frataxin Antibody, exon 4, clone 1G2 validated for use in ELISA, IC, IF & WB.
Immunofluorescence:
1:100-1:1,000. Fixation of cells in ice cold acetone or 4% paraformaldehyde is recommended. Due to the subcellular localization of frataxin in the mitochondria, cells should be permeabilized in the presence of detergent prior to incubation with primary antibody.
ELISA:
A previous lot of this antibody was used on ELISA.
Western blot (natural and recombinant protein):
1:5,000; mitochondrial preparations are recommended for consist signals (see Santos, 2001).
Optimal working dilutions must be determined by the end user.

Frataxin is the protein that is down-regulated in Friedreich ataxia (FRDA), an autosomal recessive genetic disease caused by an intronic GAA repeat expansion in intron-1 of the FXN gene. The GAA repeats result in epigenetic silencing of the FXN gene

Friedreich's ataxia (FRDA) is a neurodegenerative disorder caused by decreased expression of the mitochondrial protein frataxin. Recently we showed in a clinical pilot study in Friedreich's ataxia patients that recombinant human erythropoietin (rhuEPO) significantly increases frataxin-expression. In this in vitro
