Regulation of cell surface transferrin receptor-2 by iron-dependent cleavage and release of a soluble form

Haematologica, 2015
Transferrin receptor-2 is a transmembrane protein whose expression is restricted to hepatocytes and erythroid cells. Transferrin receptor-2 has a regulatory function in iron homeostasis, since its inactivation causes systemic iron overload.

Regulation of endocytic trafficking of transferrin receptor by optineurin and its impairment by a glaucoma-associated mutant

BMC Cell Biology, 2010
Background Optineurin is a multifunctional protein involved in several functions such as vesicular trafficking from the Golgi to the plasma membrane, NF-κB regulation, signal transduction and gene expression.

Identification and in vivo characterization of a brain-penetrating nanobody

Fluids and Barriers of the CNS, 2020
Background Preclinical models to determine blood to brain transport ability of therapeutics are often ambiguous. In this study a method is developed that relies on CNS target-engagement and is able to rank brain-penetrating capacities. This method led to

Transferrin receptor 2 and HFE regulate furin expression via mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/Erk) signaling. Implications for transferrin-dependent hepcidin regulation

Haematologica, 2010
Background Impaired regulation of hepcidin in response to iron is the cause of genetic hemochromatosis associated with defects of HFE and transferrin receptor 2.

An RNA Alternative to Human Transferrin: A New Tool for Targeting Human Cells

Molecular Therapy: Nucleic Acids, 2012
The transferrin receptor, CD71, is an attractive target for drug development because of its high expression on a number of cancer cell lines and the blood brain barrier. To generate serum-stabilized aptamers that recognize the human transferrin receptor,

Controversial Role of Transferrin in the Transport of Ruthenium Anticancer Drugs

Biomolecules, 2022
Ruthenium complexes are at the forefront of developments in metal-based anticancer drugs, but many questions remain open regarding their reactivity in biological media, including the role of transferrin (Tf) in their transport and cellular uptake. A well-

Structure of the Human Transferrin Receptor-Transferrin Complex [PDF]

Cell, 2004
Iron, insoluble as free Fe(3+) and toxic as free Fe(2+), is distributed through the body as Fe(3+) bound to transferrin (Tf) for delivery to cells by endocytosis of its complex with transferrin receptor (TfR). Although much is understood of the transferrin endocytotic cycle, little has been uncovered of the molecular details underlying the formation of

The small GTPase RAB10 regulates endosomal recycling of the LDL receptor and transferrin receptor in hepatocytes

Journal of Lipid Research, 2022
The low-density lipoprotein receptor (LDLR) mediates the hepatic uptake of circulating low-density lipoproteins (LDLs), a process that modulates the development of atherosclerotic cardiovascular disease.

Upregulation of transferrin receptor-1 induces cholangiocarcinoma progression via induction of labile iron pool

Tumor Biology, 2017
Labile iron pool is a cellular source of ions available for Fenton reactions resulting in oxidative stress. Living organisms avoid an excess of free irons by a tight control of iron homeostasis.
