Background: The iron transport protein of the blood plasma, transferrin, is maintained only with about 30% of its capacity to bind Fe3+ ions; this leaves the protein the potential ability to transport other metal ions from the bloodstream to the tissues. Scope of review: This review examines the potential role of transferrin to bind and transport alternative metal ions with possible beneficial and deleterious effects. Major conclusions: Transferrin has been postulated to play a significant role in transporting Ti4+, VO2+ (V4+), Cr3+, Ru3+, and Bi3+, all metal ions of potential therapeutic significance. Transferrin may possess a physiological role in the transport of manganese, as the trivalent ion. However, the protein may also play a role in carrying potentially toxic Al3+ and actinide ions, including Pu4+, to the tissues. Attempts to use transferrin in the selective removal of low concentrations of specific metal ions from aqueous mixed ions waste streams using a procedure called metalloprotein affinity metal chromatography are discussed. General significance: The binding of alternative metals to transferrins may have therapeutic and toxicological significance.
