CC   -!- FUNCTION: Stores iron in a soluble, non-toxic, readily available form.
CC       Important for iron homeostasis. Iron is taken up in the ferrous form
CC       and deposited as ferric hydroxides after oxidation. Also plays a role
CC       in delivery of iron to cells. Mediates iron uptake in capsule cells of
CC       the developing kidney (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Oligomer of 24 subunits. There are two types of subunits: L
CC       (light) chain and H (heavy) chain. The major chain can be light or
CC       heavy, depending on the species and tissue type. The functional
CC       molecule forms a roughly spherical shell with a diameter of 12 nm and
CC       contains a central cavity into which the insoluble mineral iron core is
CC       deposited.
CC   -!- SIMILARITY: Belongs to the ferritin family. {ECO:0000305}.
