Gene Information

human ... FXN(2395)

General description

Frataxin (FXN) protein consists of α/β fold, which is followed by the C-terminal region (CTR), with a nonperiodic structure.The gene is located on human chromosome 9q21.11.

Immunogen

FXN (AAH48097.1, 91 a.a. ~ 200 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

Frataxin (FXN) is involved in the activation of iron-sulfur cluster assembly.Overexpression of FXN in reticulocytes is associated with oxidative stress and iron status.Deficiency of FXN in human astrocytes is linked to cell death and release of neurotoxins.

Physical form

Solution in phosphate buffered saline, pH 7.4

Friedreich's ataxia (FA) is a recessive, predominantly neurodegenerative disorder caused in most cases by mutations in the first intron of the frataxin (FXN) gene. This mutation drives the expansion of a homozygous GAA repeat that results in decreased levels of
