Protein

Proton-coupled folate transporter

Gene

Slc46a1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.1 Publication

Expressioni

Tissue specificityi

Highly expressed in duodenum, especially in duodenal mucosa, the main site of intestinal heme absorption. Weakly expressed in the kidney. Not expressed in duodenum before weaning or in placenta. Weakly or not expressed in brain, heart, lung, skeletal muscle, testis and neonatal liver.1 Publication

Inductioni

Up-regulated in response to hypoxia, it is however unclear whether such up-regulation is direct or not. Not induced in the duodenum of iron-deficient mice.1 Publication
