Previous GeneCards Identifiers 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 Combined T Cell And B Cell Immunodeficiency and Gastric Adenosquamous Carcinoma. Among its related pathways are Phagosome and Clathrin derived vesicle budding. GO annotations related to this gene include poly(A) RNA binding and double-stranded RNA binding. An important paralog of this gene is FOLH1.
UniProtKB/Swiss-Prot 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.
(Microbial infection) Acts as a receptor for new-world arenaviruses: Guanarito, Junin and Machupo virus.
