PA5-27739 targets CD71 in IHC (P) and WB applications and shows reactivity with Human and mouse samples.
The PA5-27739 immunogen is recombinant fragment corresponding to a region within amino acids 169 and 407 of Human CD71.
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). A second ligand, the heditary hemochromatosis protein HFE, competes for binding with transferrin for an overlapping C-terminal binding site.
