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. Also plays a role in delivery of iron to cells. Mediates
CC iron uptake in capsule cells of the developing kidney (By similarity).
CC {ECO:0000250}.
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 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 -!- TISSUE SPECIFICITY: Ubiquitous.
CC -!- SIMILARITY: Belongs to the ferritin family. {ECO:0000305}.
