Web19 May 2024 · TFRC encodes transferrin receptor 1 (TfR1), which is the prevalent iron importer on the cell membrane. Consistently, MYCN upregulation enhances the protein level of TfR1 in NB cells (Fig. 3D ),... Web1 Dec 1998 · Tf is a serum glycoprotein that binds up to two iron atoms. TfR is a disulfide-linked homodimer present in the plasma membrane that binds one Tf molecule per TfR monomer. The Tf-TfR complex is internalized by receptor mediated endocytosis ultimately entering the endosomal compartment of the cytoplasm.

WebThe TFR2 gene, which regulates iron-binding transferrin, regulates both hepcidin and iron levels in plasma, so as to avoid iron overload when iron requirements are high, i.e., in young people. The HFE can regulate hepcidin synthesis depending on the concentration of iron in the tissue, so that iron accumulation in adults can be avoided. WebThe mechanism of iron uptake by TfR involves a selective affinity of the receptor for diferric transferrin. 1 The TfR-transferrin complex is internalized and cycled through endosomes, where the iron is released to the cytosol, with the TfR-apotransferrin complex returning to the extracellular surface (Fig. 1). At the surface the apotransferrin ...
