Protein

Ferritin, spleen middle subunit

Gene
N/A
Organism
Trematomus bernacchii (Emerald rockcod) (Pagothenia bernacchii)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein 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

Catalytic activityi

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

pH dependencei

Stable at acidic pHs.1 Publication
