CC   -!- FUNCTION: Stores iron in a soluble, non-toxic, readily available form.
CC       Important for iron homeostasis. Has ferroxidase activity. Iron is taken
CC       up in the ferrous form and deposited as ferric hydroxides after
CC       oxidation.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4 Fe(2+) + 4 H(+) + O2 = 4 Fe(3+) + 2 H2O;
CC         Xref=Rhea:RHEA:11148, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15379, ChEBI:CHEBI:29033, ChEBI:CHEBI:29034; EC=1.16.3.1;
CC   -!- SUBUNIT: Oligomer of 24 subunits. There are at least two types of
CC       subunits. The functional molecule forms a roughly spherical shell with
CC       a diameter of 12 nm and contains a central cavity into which the
CC       insoluble mineral iron core is deposited.
CC   -!- TISSUE SPECIFICITY: Liver, gonads, head kidney, heart and spleen.
CC   -!- SIMILARITY: Belongs to the ferritin family. {ECO:0000305}.
