Ferritin

Function Ferritin (FR) is an iron storage and release protein. It stores iron as microcrystals with phosphate and hydroxide ions. FR is composed of 24 subunits of heavy chain (FTH) and light chain (FTL). Amphibians have an additional middle subunit FR (FTM). Bacterioferritin (BFR) structure is very similar to FR. It contains a binuclear iron center and haem. It stores iron as ferric oxide mineral in its hollow central cavity. Thioferritin (TFR) is a ferritin-related protein with 2 cysteine residues adjacent to the dimetal binding site. Another iron storing protein is the DNA-binding Protein of Starved cells (Dps) - a ferritin-like diiron carboxylate. MrgA – another iron storage protein - belongs to the Dps family. Relevance Cavities formed by FR are used for the manufacture of nanoparticles. FR is used as a marker for iron overload disorder. Disease FR deficiency can lead to anemia.
