  • 描述
    小鼠单克隆抗体[MEM-189] to Transferrin Receptor
  • 特异性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.

  • 功能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.
  • 疾病相关Immunodeficiency 46
  • 序列相似性Belongs to the peptidase M28 family. M28B subfamily.
    Contains 1 PA (protease associated) domain.
  • 翻译后修饰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.
  • 细胞定位Secreted and Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

  • ab1086 staining Transferrin Receptor in Human PC-3 prostate cancer cell line by Flow Cytometry. The sample was incubated with the primary antibody (0.3µg/ml in PBS + 2% FBS) for 1 hour at 4°C. An Alexa Fluor® 488-conjugated Goat anti-mouse IgG (1/500) was used as the secondary antibody.
    Gating Strategy: Cells gated for live and singlets.

  • ab1086 at 1/100 dilution, staining Transferrin Receptor in rat mesenchymal stem cells by Immunocytochemistry/ Immunofluorescence. The cells were fixed with 4% paraformaldehyde for 10 min at room temperature, washed with PBS (pH 7.4) and incubated with 10% serum plus background reducing components, for 30 min at room temperature. A Fluorescene conjugated anti-mouse IgG was used as secondry antibody and observed under an epi-fluorescence microscope (Nikon, Tokyo, Japan).
