  • Function
    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).
  • Tissue specificity
    Expressed in placenta, intestine, muscle and spleen.
  • Involvement in disease
    Defects in SLC40A1 are the cause of hemochromatosis type 4 (HFE4) [MIM:606069]. HFE4 is an autosomal dominant iron-loading disorder characterized by early iron accumulation in reticuloendothelial cells and a marked increase in serum ferritin before elevation of the transferrin saturation.
  • Sequence similarities
    Belongs to the SLC40A transporter family.
  • Cellular localization
    Cell membrane. Localized to the basolateral membrane of polarized epithelial cells.

  • ab78066, at 20µg/ml, staining SLC40A1 in human skeletal muscle by Immunohistochemistry using formalin-fixed, paraffin-embedded tissue.
    A heat induced antigen retrieval step was performed using pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen.
  • ICC/IF image of ab78066 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab78066, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • Immunohistochemical staining of paraffin embedded, formalin fixed, kidney renal tubular epithelium using ab78066 at 20 µg/mL.

  • Negative control - immunohistochemical staining of paraffin embedded, formalin fixed, breast epithelium using ab78066 at 20 µg/mL.
