{"product_id":"tfr1-rabbit-polyclonal-antibody-100ul","title":"TFR1 Rabbit Polyclonal Antibody, 100ul","description":"\u003cp\u003eCellular 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.|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).|Belongs to the peptidase M28 family. M28B subfamily.|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","brand":"BT LAB","offers":[{"title":"Default Title","offer_id":56512710050165,"sku":"BT-AP13013-100ul","price":247.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/Antibody_main_1.jpg?v=1766393459","url":"https:\/\/www.labcart.com\/products\/tfr1-rabbit-polyclonal-antibody-100ul","provider":"LabCart Life Science","version":"1.0","type":"link"}
