Protein
Ferritin, middle subunit
Gene
N/A
Organism
Trematomus newnesi (Dusky notothen)
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

Subunit structurei

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.1 Publication
