Entrez Gene Summary for TFRC Gene

  • This gene encodes a cell surface receptor necessary for cellular iron uptake by the process of receptor-mediated endocytosis. This receptor is required for erythropoiesis and neurologic development. Multiple alternatively spliced variants have been identified. [provided by RefSeq, Sep 2015]

GeneCards Summary for TFRC Gene

TFRC (Transferrin Receptor) is a Protein Coding gene. Diseases associated with TFRC include Immunodeficiency 46 and Combined Immunodeficiency, X-Linked. Among its related pathways are Vesicle-mediated transport and Phagosome. Gene Ontology (GO) annotations related to this gene include double-stranded RNA binding. An important paralog of this gene is TFR2.

UniProtKB/Swiss-Prot Summary for TFRC Gene

  • 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.
