TFRC

Transferrin receptor protein 1 (TfR1) also known as (Cluster of Differentiation 71) (CD71) is a is_associated_with::protein that in humans is encoded by the TFRC is_associated_with::gene. TfR1 is required for iron delivery from is_associated_with::transferrin to cells.

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

Clinical significance
CD71 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
TFRC has been shown to interact with is_associated_with::GABARAP and HFE.
