Molecular cloning of a partial cDNA of a novel gene in iron metabolism

In order to elucidate the possible role played by human hepatic ferritin-associated protein in normal cellular iron metabolism and in iron overload diseases, malignancies and hepatic fibrosis, we attempted to isolate genes for ferritin associated proteins. Here we describe the cloning of a novel cDNA fragment of a 10 kb mRNA transcript from human liver and human T lymphoid (MOLT-4) cells using a short degenerate 5'-primer derived from six amino acid residues of an affinity purified ferritin associated protein from human liver. Northern analysis of this clone has revealed the presence of a 10 kb mRNA species in both human liver and MOLT-4 cell RNA.
