Product nameAnti-Transferrin Receptor antibody [B349 (DF1513)]
See all Transferrin Receptor primary antibodies
DescriptionMouse monoclonal [B349 (DF1513)] to Transferrin Receptor
SpecificityThis antibody reacts with the transferrin receptor, a 180-190 kD transmembrane glycoprotein which exists as a 95 kD homodimer with interchain disulfide bond. The specificity of these antibodies, as demonstrated by immunoprecipitation, are equivalent to OKT9, B3/25 and BerT9. This antibody reacts with many proliferating cells in both normal and neoplastic tissues. It also reacts with renal tubular epithelium, islets of Langerhans, scattered cells in the anterior pituitary, hepatocytes and most tissue macrophages.

FunctionCellular uptake of iron occurs via receptor-mediated endocytosis of ligand-occupied transferrin receptor into specialized endosomes. Endosomal acidification leads to iron release. The apotransferrin-receptor complex is then recycled to the cell surface with a return to neutral pH and the concomitant loss of affinity of apotransferrin for its receptor. Transferrin receptor is necessary for development of erythrocytes and the nervous system (By similarity). A second ligand, the heditary hemochromatosis protein HFE, competes for binding with transferrin for an overlapping C-terminal binding site. Positively regulates T and B cell proliferation through iron uptake (PubMed:26642240).
(Microbial infection) Acts as a receptor for new-world arenaviruses: Guanarito, Junin and Machupo virus.
Involvement in diseaseImmunodeficiency 46
Sequence similaritiesBelongs to the peptidase M28 family. M28B subfamily.
Contains 1 PA (protease associated) domain.
modificationsN- and O-glycosylated, phosphorylated and palmitoylated. The serum form is only glycosylated.
Proteolytically cleaved on Arg-100 to produce the soluble serum form (sTfR).
Palmitoylated on both Cys-62 and Cys-67. Cys-62 seems to be the major site of palmitoylation.
Cellular localizationSecreted and Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
