RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable several functions, including 2 iron, 2 sulfur cluster binding activity; ferroxidase activity; and iron ion binding activity. Involved in determination of adult lifespan; response to hydrogen peroxide; and response to superoxide. Located in mitochondrion. Is expressed in amphid neurons; body wall musculature; intestine; pharyngeal muscle cell; and spermatheca. Used to study Friedreich ataxia. Human ortholog(s) of this gene implicated in Friedreich ataxia; Friedreich ataxia 1; glioblastoma; and type 2 diabetes mellitus. Orthologous to human FXN (frataxin).

What's a GeneRIF?

Demonstrate a causal connection between induction of autophagy and lifespan extension following reduced frataxin expression.
Title: Autophagy induction extends lifespan and reduces lipid content in response to frataxin silencing in C. elegans.
Frataxin suppression by RNAi significantly reduces lifespan in C. elegans.
Title: Impaired respiration is positively correlated with decreased life span in Caenorhabditis elegans models of Friedreich Ataxia.
Study describes in detail the structure of all of the coding units within the CEOP2232 operon, coding for frataxin; it is composed of eight genes of a diverse nature, organized in a complex structure.
Title: The frataxin-encoding operon of Caenorhabditis elegans shows complex structure and regulation.
The genomic structure of frh-1, the development of an RNA interference model, and the interaction of frh-1 with mev-1 are reported.
Title: Reduction of Caenorhabditis elegans frataxin increases sensitivity to oxidative stress, reduces lifespan, and causes lethality in a mitochondrial complex II mutant.
Frataxin suppression by RNAi significantly extends lifespan in C. elegans.
Title: Reduced expression of frataxin extends the lifespan of Caenorhabditis elegans.
