[[Ferritin]] (FR) is an iron storage and release protein. It stores iron as microcrystals with phosphate and hydroxide ions. FR is composed of 24 subunits of heavy chain (FTH) and light chain (FTL).<ref>PMID:20304033</ref> Amphibians have an additional middle subunit FR (FTM).<br /> | [[Ferritin]] (FR) is an iron storage and release protein.
