== Function ==
[https://www.uniprot.org/uniprot/FRIH_HUMAN FRIH_HUMAN] 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. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity).

== Publication Abstract from PubMed ==
We describe here the construction of a three-dimensional, porous, crystalline framework formed by spherical protein nodes that assemble into a prescribed lattice arrangement through metal-organic linker-directed interactions. The octahedral iron storage en-zyme, ferritin, was engineered in its C3 symmetric pores with tripodal Zn coordination sites. Dynamic light scat-tering and crystallographic studies established that this Zn-ferritin construct could robustly self-assemble into the desired bcc-type crystals upon coordination of a ditopic linker bearing hydroxamic acid functional groups. This system represents the first example of a ternary protein-metal-organic crystalline framework whose formation is fully dependent on each of its three components.
