Names and origin

Protein attributes

Sequence length176 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation By similarity. UniProtKB P07798

Catalytic activity

4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O. Ref.1

Subunit structure

In liver, forms a heteropolymer consisting of middle and heavy subunits. In spleen, forms a homopolymer. The functional molecule forms a roughly spherical shell with a diameter of 12 nm and contains a central cavity into which the insoluble mineral iron core is deposited. Ref.1

Tissue specificity

Liver and spleen (at protein level). Ref.1

Sequence similarities

Belongs to the ferritin family.

Contains 1 ferritin-like diiron domain.

Biophysicochemical properties

Temperature dependence:

Thermostable. Ref.1
