Transferrin (IPR016357)

Short name: Transferrin

Family relationships


Transferrins are eukaryotic iron-binding glycoproteins with the ability to bind ferric iron with high affinity in the cleft of each of two homologous lobes. They control the level of free iron in biological fluids [PMID: 3032619]. Members of the family include blood serotransferrin (siderophilin), milk lactotransferrin (lactoferrin), egg white ovotransferrin (conalbumin) and membrane-associated melanotransferrin. Family members that do no bind iron have also been discovered, including inhibitor of carbonic anhydrase (ICA), which strongly binds to and inhibits certain isoforms of carbonic anhydrase [PMID: 20572014].
