Transferrin receptor protein 1 (TfR1), also known as Cluster of Differentiation 71 (CD71), is a protein that in humans is encoded by the TFRC gene.[5][6] TfR1 is required for iron import from transferrin into cells by endocytosis.[7][8]

Structure and function

TfR1 = transferrin receptor 1 in Human iron metabolism.

TfR1 is a transmembrane glycoprotein composed of two disulfide-linked monomers joined by two disulfide bonds. Each monomer binds one holo-transferrin molecule creating an iron-Tf-TfR complex which enters the cell by endocytosis.[9]

Clinical significance

TfR1 as a potential new target in cases of human leukemia & lymphoma. InatherYs, in Évry, France, developed a candidate drug, INA01 antibody (anti-CD71) that showed efficacy in pre-clinical studies in the therapy of two incurable orphan oncohematological diseases: the adult T cell leukemia (ATLL) caused by HTLV-1 and the Mantle cell lymphoma (MCL).

Interactions

TfR1 has been shown to interact with GABARAP[10] and HFE.[11][12]
