产品介绍background:
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. Useful in studies of dividing haematopoietic and tumour cell populations, and metabolic activity. A second ligand, the heditary hemochromatosis protein HFE, competes for binding with transferrin for an overlapping C terminal binding site. The antigen is present on most dividing cells, including normally cycling in vivo hematopoietic progenitor cells, mitogenically stimulated cells in vitro, some primary tumor cells and most proliferating cells in vitro.

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 heditary hemochromatosis protein HFE, competes for binding with transferrin for an overlapping C-terminal binding site.

Subunit:
Homodimer; disulfide-linked. Binds one transferrin molecule per subunit. Interacts with SH3BP4.

Subcellular Location:
Secreted and Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

CD71/Transferrin receptor,转铁蛋白受体抗体Post-translational modifications:
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.

Similarity:
Belongs to the peptidase M28 family. M28B subfamily.
Contains 1 PA (protease associated) domain.

转铁蛋白及转铁蛋白受体(TfnrR)是机体铁代谢中的重要因子，铁是细胞生长增殖、代谢的必需元素,转铁蛋白受体(TfR)介导的胞吞作用是细胞摄取铁的主要途径。肿瘤细胞因增殖生长旺盛,对铁的需求高,所以肿瘤细胞有比正常细胞更多的转铁蛋白受体的表达。
