frataxin, mitochondrial [Phasianus colchicus]

Protein Classification

frataxin( domain architecture ID 10022430)

frataxin is a mitochondrial protein that promotes the biosynthesis of heme and assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways

frataxin; Frataxin is a mitochondrial protein, mutation of which leads to the disease Friedreich's ataxia. Its orthologs are widely distributed in the bacteria, associated with the ISC system for iron-sulfur cluster assembly, and designated CyaY. This exception-type model allows those examples of frataxin per se that score above the trusted cutoff to the CyaY equivalog-type model (TIGR03421) to be named appropriately.

Frataxin-like domain; This family contains proteins that have a domain related to the globular C-terminus of Frataxin the protein that is mutated in Friedreich's ataxia. This domain is found in a family of bacterial proteins. The function of this domain is currently unknown. It has been suggested that this family is involved in iron transport.

Frataxin is a nuclear-encoded mitochondrial protein implicated in Friedreich's ataxia (FRDA), an human autosomal recessive neurodegenerative disease; Frataxin is found in eukaryotes and in purple bacteria; lack of frataxin causes iron to accumulate in the mitochondrial matrix suggesting that frataxin is involved in mitochondrial iron homeostasis and possibly in iron transport; the domain has an alpha-beta fold consisting of two helices flanking an antiparallel beta sheet.

 75-184 5.84e-30

iron donor protein CyaY; Members of this protein family are the iron-sulfur cluster (FeS) metabolism protein CyaY, a homolog of eukaryotic frataxin. ISC is one of several bacterial systems for FeS assembly; we find by Partial Phylogenetic Profiling vs. the ISC system that CyaY most like work with the ISC system for FeS cluster biosynthesis. A study of of cyaY mutants in Salmonella enterica bears this out. Although the trusted cutoff is set low enough to include eukaryotic frataxin sequences, a narrower, exception-type model (TIGR03421) identifies identifies members of that specific set.
