  • Function
    Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. It is responsible for the transport of iron from sites of absorption and heme degradation to those of storage and utilization. Serum transferrin may also have a further role in stimulating cell proliferation.
  • Tissue specificity
    Expressed by the liver and secreted in plasma.
  • Involvement in disease
    Defects in TF are the cause of atransferrinemia (ATRAF) [MIM:209300]. Atransferrinemia is rare autosomal recessive disorder characterized by iron overload and hypochromic anemia.
  • Sequence similarities
    Belongs to the transferrin family.
    Contains 2 transferrin-like domains.
  • Cellular localization
    Secreted.
  • Information by UniProt
