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.

Catalytic activity

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

Subunit structure

Oligomer of 24 subunits. The functional molecule is roughly spherical and contains a central cavity into which the polymeric mineral iron core is deposited By similarity.

Miscellaneous

There are three types of ferritin subunits in amphibia: L, M and H chains. M and H chains are fast mineralizing; the L chain is very slow mineralizing By similarity.

Sequence similarities

Belongs to the ferritin family.

Contains 1 ferritin-like diiron domain.
