We have isolated essentially full-length cDNA clones for human ferritin H and L chains from a human liver cDNA library. This allows the first comparison of H and L nucleotide and amino acid sequences from the same species as well as ferritin L cDNA sequences from different species. We conclude that human H and L ferritins are related proteins which diverged about the time of evolution of birds and mammals. We also deduce the secondary structure of the H and L subunits and compare this with the known structure of horse spleen ferritin. We find that residues involved in subunit interaction in shell assembly are highly conserved in H and L sequences. However, we find several interesting differences in H subunits at the amino acid residues involved in iron transport and deposition. These substitutions could account for known differences in the uptake, storage, and release of iron from isoferritins of different subunit composition.
