Summary: Predicted to enable several functions, including 2 iron, 2 sulfur cluster binding activity; ferroxidase activity; and iron ion binding activity. Acts upstream of or within several processes, including adult walking behavior; negative regulation of organ growth; and proprioception. Located in mitochondrion. Is expressed in several structures, including brain; cartilage condensation; heart; hemolymphoid system; and lower jaw incisor. Used to study Friedreich ataxia. Human ortholog(s) of this gene implicated in Friedreich ataxia; Friedreich ataxia 1; and type 2 diabetes mellitus. Orthologous to human FXN (frataxin).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
