UniProtKB - Q923U9 (S40A1_RAT)
Protein
Solute carrier family 40 member 1
Gene
Slc40a1
Organism
Rattus norvegicus (Rat)
Status
Functioni
May be involved in iron export from duodenal epithelial cell and also in transfer of iron between maternal and fetal circulation. Mediates iron efflux in the presence of a ferroxidase (hephaestin and/or ceruloplasmin) (By similarity).By similarity
