Ferriitin
Ferritin, sometimes misspelled ferriitin, is an intracellular protein complex that stores iron and releases it in a controlled manner to maintain iron homeostasis in the body. It is found in nearly all organisms and tissues, with high concentrations in the liver, spleen, and bone marrow, and it also circulates in the blood as serum ferritin.
Structurally, ferritin forms a nearly spherical shell composed of 24 subunits, arranged as a protein cage with
Biologically, ferritin serves two main roles: iron storage and iron release as needed by cellular processes.
Genes encoding ferritin subunits include FTH1 (heavy chain) and FTL (light chain) in humans. Beyond its physiological
