TFRC, also known as transferrin receptor protein 1, is a transmembrane glycoprotein composed of two disulfide-linked monomers joined by two disulfide bonds. It acts as cellular uptake of iron occurs via receptor-mediated endocytosis of ligand-occupied transferrin receptor into specialized endosomes. This protein is necessary for development of erythrocytes and the nervous system. And it is positively regulates T and B cell proliferation through iron uptake.
