CRYSTAL STRUCTURES OF MUTANT (K206A) THAT ABOLISH THE DILYSINE INTERACTION IN THE N-LOBE OF HUMAN TRANSFERRIN
Template:ABSTRACT PUBMED 11327820
Disease
[TRFE_HUMAN] Defects in TF are the cause of atransferrinemia (ATRAF) [MIM:209300]. Atransferrinemia is rare autosomal recessive disorder characterized by iron overload and hypochromic anemia.[1][2]
Function
[TRFE_HUMAN] 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.
