A list of abbreviations and the functions of iron related proteins.

	Abbreviation	Function
Divalent metal transporter 1	DMT1	Cellular iron importer responsible for ferrous iron uptake
Ferroportin1	FPN1	Cellular iron exporter responsible for ferrous iron release
Ceruloplasmin	Cp	A ferroxidase mediating oxidization of Fe2+ to Fe3+ and promoting FPN1-mediated iron release
Transferrin/transferrin receptor 1	Tf/TfR1	A major pathway for Fe3+ ions acquisition to cells by a receptor-mediated pathway
Lactoferrin/lactoferrin receptor	Lf/LfR	Transfers Fe3+ ions to cells by a receptor-mediated pathway
Ferritin	Ferritin	Intracellular iron-storage protein, keeping iron in a non-toxic form
Hepcidin	Hepcidin	A circulating peptide that binds to FPN1, mediating degradation of FPN1
