General description
A shell of 24 protein subunits (apoferritin) and a core Fe 3+ ions with a peptide MW of 440 kDa. Review of the ferritin-like superfamily of iron-storage proteins, virtually ubiquitous in life on earth.
Application
Biochem/physiol Actions
A ubiquitous iron storage protein that plays a key role in iron metabolism. It serves as an intracellular iron reserve (particularly in spleen, liver, intestinal mucosa, and bone marrow) and functions in iron detoxification.
A ubiquitous iron storage protein that plays a key role in iron metabolism. It serves as an intracellular iron reserve (particularly in spleen, liver, intestinal mucosa, and bone marrow) and functions in iron detoxification. Studies have shown that ferritin iron incorporation is mediated by a ferroxidase activity associated with ferritin H subunits and a nucleation center associated with ferritin L subunits. Release of iron from ferritin has an essential role in iron-dependent lipid peroxidation and may contribute to free radical-induced cell damage in vivo. Therefore, by binding iron, ferritin may function as an antioxidant.

Ferritin, the iron-storing protein, speeds up proton transverse magnetic relaxation in aqueous solutions. This T(2) shortening is used in MRI to quantify iron in the brain and liver. Current theoretical models underestimate the relaxation enhancement by ferritin at imaging fields

Iron and oxygen chemistry is mediated by iron proteins for many biological functions.
