Protein

Ferritin heavy chain A

Gene

fth1-a

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

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).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).By similarity

Catalytic activityi

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