frh-1 encodes the C. elegans frataxin ortholog; by homology, FRH-1 is predicted to be a mitochondrial protein required for biogenesis of iron-sulfur clusters, co-factors necessary for proper function of electron transport chain proteins; in C. elegans, loss of frh-1 activity via RNAi results in small body size, pale coloration, reduced motility, decreased pharyngeal pumping and defecation, reduced egg-laying and fertility, hypersensitivity to oxidative stress, and altered adult lifespan; an frh-1::gfp promoter fusion is expressed in neurons, the pharynx, gut, spermatheca and body wall muscle; in the pharynx, FRH-1 localizes to the mitochondria.
