Protein Structure

UniProt Annotation

Function

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). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Melanosome {ECO:0000250}.
