Detection of Human TfR2 by Western Blot. Western blot shows lysates of human liver tissue and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human TfR2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3120) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for TfR2 at approximately 100 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Transferrin Receptor 2 (TfR2) is an iron-binding protein that is homologous to the transferrin receptor. Lack of active TfR2 has been associated with a rare form of hemochromatosis. The TfR2 alpha isoform is a type 2 transmembrane protein that is expressed in the liver and modulates hepcidin production in response to iron. It forms a 215 kDa disulfide-linked homodimer that is presumably glycated. The TfR2 beta isoform lacks the intracellular, transmembrane and part of the extracellular regions and is expressed ubiquitously. The extracellular portion of human TfR2 shares 86% aa identity with mouse.
