  • 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.
  • Post-translational
    N- 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.
