Protein Structure
UniProt Annotation
Function Ferric-chelate reductase that reduces Fe(3+) to Fe(2+). Present at the brush border of duodenal enterocytes where it probably reduces dietary Fe(3+) thereby facilitating its transport into the mucosal cells. Uses ascorbate as electron donor. May be involved in extracellular ascorbate recycling in erythrocyte membranes. May also act as a ferrireductase in airway epithelial cells. {ECO:0000269PubMed:16521311, ECO:0000269PubMed:16521312, ECO:0000269PubMed:17068337, ECO:0000269PubMed:19673882}.
Subcellular Localization Membrane {ECO:0000269PubMed:12949720}; Multi-pass membrane protein {ECO:0000269PubMed:12949720}.
Disease Associations
Tissue Specificity Present in erythrocyte membranes (at protein level). Also expressed in respiratory epithelium. {ECO:0000269PubMed:16510471, ECO:0000269PubMed:17068337}.
