Also known as CD71TFR1p90
Summary
TFRC (transferrin receptor, HGNC:11763) is a protein-coding gene on chromosome 3q29, encoding Transferrin receptor protein 1 (P02786). Cellular uptake of iron occurs via receptor-mediated endocytosis of ligand-occupied transferrin receptor into specialized endosomes. It is a selective cancer dependency (DepMap: 71.8% of cell lines).
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.

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. A second ligand, the hereditary 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. Acts as a lipid sensor that regulates mitochondrial fusion by regulating activation of the JNK pathway. When dietary levels of stearate (C18:0) are low, promotes activation of the JNK pathway, resulting in HUWE1-mediated ubiquitination and subsequent degradation of the mitofusin MFN2 and inhibition of mitochondrial fusion. When dietary levels of stearate (C18:0) are high, TFRC stearoylation inhibits activation of the JNK pathway and thus degradation of the mitofusin MFN2. Mediates uptake of NICOL1 into fibroblasts where it may regulate extracellular matrix production. (Microbial infection) Acts as a receptor for new-world arenaviruses: Guanarito, Junin and Machupo virus. (Microbial infection) Acts as a host entry factor for rabies virus that hijacks the endocytosis of TFRC to enter cells. (Microbial infection) Acts as a host entry factor for SARS-CoV, MERS-CoV and SARS-CoV-2 viruses that hijack the endocytosis of TFRC to enter cells. (Microbial infection) Acts as a receptor for Plasmodium vivax.
Subunit / interactions. Homodimer; disulfide-linked. Binds one transferrin or HFE molecule per subunit. Binds the HLA class II histocompatibility antigen, DR1. Interacts with SH3BP3. Interacts with STEAP3; facilitates TFRC endocytosis in erythroid precursor cells. Interacts with GRM2. Interacts with SNX32; the interaction is involved in intracellular trafficking of the receptor. (Microbial infection) Interacts with Guanarito, Junin and Machupo arenavirus glycoprotein complex. (Microbial infection) Interacts with rabies virus protein G. (Microbial infection) Interacts with SARS-CoV-2 spike protein S. (Microbial infection) Interacts with Plasmodium vivax RBP2b; the interaction mediates parasite invasion into human reticulocytes.
Subcellular location. Cell membrane. Melanosome Secreted.
Post-translational modifications. Stearoylated by ZDHHC6 which inhibits TFRC-mediated activation of the JNK pathway and promotes mitochondrial fragmentation. Stearoylation does not affect iron uptake. 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.
Disease relevance. Immunodeficiency 46 (IMD46) [MIM:616740] An autosomal recessive primary immunodeficiency disorder characterized by early-onset chronic diarrhea, recurrent infections, hypo- or agammaglobulinemia, normal lymphocyte counts, intermittent neutropenia, and intermittent thrombocytopenia. The disease is caused by variants affecting the gene represented in this entry.
Induction. Regulated by cellular iron levels through binding of the iron regulatory proteins, IRP1 and IRP2, to iron-responsive elements in the 3’-UTR. Up-regulated upon mitogenic stimulation.
Miscellaneous. Serum transferrin receptor (sTfR) is used as a means of detecting erythropoietin (EPO) misuse by athletes and as a diagnostic test for anemia resulting from a number of conditions including rheumatoid arthritis, pregnancy, irritable bowel syndrome and in HIV patients. Canine and feline parvoviruses bind human and feline transferrin receptors and use these receptors to enter and infect cells.
Similarity. Belongs to the peptidase M28 family. M28B subfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 142 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
