Description
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.

Descripción
TFRC, also known as CD71, is a transmembrane glycoprotein that mediates the uptake of transferrin-bound iron into cells via receptor-mediated endocytosis. It plays a crucial role in iron homeostasis, as iron is essential for processes like DNA synthesis, oxygen transport, and energy metabolism. TFRC expression is tightly regulated by cellular iron levels, proliferative demand, and hypoxia, with high expression observed in rapidly dividing cells, such as activated lymphocytes, erythroid progenitors, and cancer cells. Its overexpression is frequently observed in tumors, where increased iron uptake supports cancer cell proliferation and survival. TFRC is also involved in immune regulation and erythropoiesis, with its deficiency leading to anemia, impaired cell growth, and compromised immune responses. Targeting TFRC is being explored in cancer therapy as a mechanism for selective drug delivery and iron deprivation. Knockdown studies show impaired iron metabolism, reduced cell proliferation, and increased sensitivity to oxidative stress, emphasizing its central role in cellular growth, iron transport, and metabolic regulation.

anti- CD71 antibody
CD71, also known as transferrin receptor protein 1(TfR1), is a transmembrane glycoprotein composed of two disulfide-linked monomers, each of 90 kDa molecular weight. Each monomer binds one holo-transferrin molecule creating an iron-Tf-TfR complex which enters the cell by endocytosis. CD71 is present on actively proliferating cells and is essential for iron transport into proliferating cells.
