Transferrin Receptor (转铁蛋白受体)

Transferrin Receptor is a transmembrane glycoprotein. Transferrin Receptor consists of two isoforms, TfR1 and TfR2. Transferrin Receptor mediates the uptake of transferrin-iron complexes. Transferrin Receptor plays an important role in iron homeostasis as a gatekeeper regulating transferrin iron uptake. Transferrin Receptor is also considered as a proliferation marker and an attractive target for anticancer agents (e.g., a marker of poor prognosis in breast cancer). Transferrin Receptor is associated with a variety of cancers including acute leukemia and breast cancer^{[1][2][3][4][5][6]}.
