產(chǎn)品介紹   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 (By similarity). 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 transferring for an overlapping C-terminal binding site.

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.

Subcellular Location:
Cell membrane; Single-pass type II membrane protein. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
Transferrin receptor protein 1, serum form: Secreted

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.

轉(zhuǎn)鐵蛋白及轉(zhuǎn)鐵蛋白受體(TfnrR)是機體鐵代謝中的重要因子，鐵是細胞生長增殖、代謝的必需元素,轉(zhuǎn)鐵蛋白受體(TfR)介導的胞吞作用是細胞攝取鐵的主要途徑。腫瘤細胞因增殖生長旺盛,對鐵的需求高,所以腫瘤細胞有比正常細胞更多的轉(zhuǎn)鐵蛋白受體的表達。
