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.,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:Canine and feline parvoviruses bind human and feline transferrin receptors and use these receptors to enter and infect cells.,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.,PTM:N- and O-glycosylated, phosphorylated and palmitoylated. The serum form is only glycosylated.,PTM:Palmitoylated on both Cys-62 and Cys-67. Cys-62 seems to be the major site of palmitoylation.,PTM:Proteolytically cleaved on Arg-100 to produce the soluble serum form (sTfR) .,similarity:Belongs to the peptidase M28 family. M28B subfamily.,similarity:Contains 1 PA (protease associated) domain.,subcellular location:Identified by mass spectrometry in melanosome fractions from stage I to stage IV.,subunit:Homodimer; disulfide-linked. Binds one transferrin or HFE molecule per subunit. Binds the HLA class II histocompatibility antigen, DR1. Interacts with SH3BP3. Interacts with Machupo arenavirus GPC.,\u003c\/p\u003e\n\n\u003cp\u003eCondition: Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.\u003c\/p\u003e\n\n\u003cp\u003eStorage Instructions: -20°C\/1 year\u003c\/p\u003e\n\n\u003cp\u003eRecommended dilutions: WB 1:1000-2000 ELISA 1:5000-20000\u003c\/p\u003e\n\n\u003cp\u003eAlternative Names: Transferrin receptor protein 1 (TR;TfR;TfR1;Trfr;T9;p90;CD antigen CD71) [Cleaved into: Transferrin receptor protein 1, serum form (sTfR) ]\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB; ELISA\u003c\/p\u003e\n\n\u003cp\u003eSpecies Cross-Reactivity: Human; Mouse\u003c\/p\u003e\n\n\u003cp\u003eGeneID (Human): 7037\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P02786\u003c\/p\u003e\n\n\u003cp\u003eSource: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"Reed Bio","offers":[{"title":"50μL","offer_id":45119736774835,"sku":"RA23090-50","price":336.0,"currency_code":"CAD","in_stock":true},{"title":"100μL","offer_id":45119736807603,"sku":"RA23090-100","price":448.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/logo_0930af85-fdda-4caa-a951-029445b95382.png?v=1773356444","url":"https:\/\/afsbio.com\/products\/cd71-tfr-rabbit-polyclonal-antibody-ra23090","provider":"AFSBio Inc.","version":"1.0","type":"link"}
