Anti-Transferrin Receptor antibody [MEM-189] (ab1086)

Overview

  • Product name
    Anti-Transferrin Receptor antibody [MEM-189]
    See all Transferrin Receptor primary antibodies
  • Description
    Mouse monoclonal [MEM-189] to Transferrin Receptor
  • Host species
    Mouse
  • Specificity
    The antibody MEM-189 reacts with CD71 antigen (transferrin receptor), a 95 kDa type II homodimeric transmembrane glycoprotein expressed on activated B and lymphocytes, macrophages and erythroid precursors; it is lost on resting blood leukocytes. The antibody MEM-189 does not block binding of transferrin to the receptor.
  • Tested applications
    Suitable for: IHC-FrFl, Flow Cyt, IP, WBmore details
    Unsuitable for: ICC/IF
  • Species reactivity

  • Target

    • Function
      Cellular 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 disease
      Immunodeficiency 46
    • Sequence similarities
      Belongs to the peptidase M28 family. M28B subfamily.
      Contains 1 PA (protease associated) domain.
    • Post-translational
      modifications
      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 localization
      Secreted and Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
