Inactivation of the murine Transferrin Receptor 2 gene using the Cre recombinase: LoxP system

Transferrin Receptor 2 (TfR2) is a key molecule involved in the regulation of iron homeostasis. Mutations in TfR2 lead to type 3 hemochromatosis in humans. We have developed mice with a targeted deletion of TfR2. The Cre-recombinase:loxP system used to create the mice allows both full deletion and tissue-specific deletion of TfR2. The development of these mice will provide new models for type 3 hemochromatosis and assist in determining the role of TfR2 in iron metabolism.
