Function Has been shown to act both as an intestinal proton- coupled high-affinity folate transporter and as an intestinal heme transporter which mediates heme uptake from the gut lumen into duodenal epithelial cells. The iron is then released from heme and may be transported into the bloodstream. Dietary heme iron is an important nutritional source of iron. Shows a higher affinity for folate than heme. {ECO:0000269|PubMed:17129779, ECO:0000269|PubMed:17156779, ECO:0000269|PubMed:17446347, ECO:0000269|PubMed:17475902}.
Subcellular Location Apical cell membrane; Multi-pass membrane protein. Cytoplasm {ECO:0000250}. Note=Localizes to the apical membrane of intestinal cells in iron-deficient cells, while it resides in the cytoplasm in iron-replete cells. {ECO:0000250}.
Tissue Specificity Expressed in kidney, liver, placenta, small intestine, spleen, retina and retinal pigment epithelium. Lower levels found in colon and testis. Very low levels in brain, lung, stomach, heart and muscle. In intestine, expressed in duodenum with lower levels in jejunum, ileum, cecum, rectum and segments of the colon. {ECO:0000269|PubMed:17129779, ECO:0000269|PubMed:17335806}.
