Protein Structure

UniProt Annotation

Function

Important in metal transport, in particular iron. Involved in apical iron uptake into duodenal enterocytes. Involved in iron transport from acidified endosomes into the cytoplasm of erythroid precursor cells. May play an important role in hepatic iron accumulation and tissue iron distribution. {ECO:0000269PubMed:11739192, ECO:0000269PubMed:15849611}.

Subcellular Localization

Endosome membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.

Disease Associations

Note=Defects in Slc11a2 are the cause of microcytic anemia (mk). Homozygous mk/mk mice have hypochromic microcytic anemia due to severe defects in intestinal iron absorption and erythroid iron utilization.

Tissue Specificity

Isoform 2 is abundantly expressed in erythroid precursor cells (at protein level). Expressed at low levels in most tissues analyzed. Expressed at low levels in small intestine and at higher levels in kidney. {ECO:0000269PubMed:10361139, ECO:0000269PubMed:11739192}.
