Probable vacuolar iron transporter involved in the transfer of iron ions from the cytosol to the vacuole for intracellular iron storage (PubMed:25360591). Involved in regulation of cellular iron homeostasis (PubMed:25360591). Vacuolar iron storage is required for seed embryo and seedling development (PubMed:25360591). Expressed in the vascular bundles of the shoot and the stele of the root. Expressed in inflorescences and at lower levels in leaves. Down-regulated under iron deficiency (PubMed:21411332, PubMed:25360591). Induced by iron supply (PubMed:25360591). Can mediate sequestration of iron ions into vacuoles when expressed in the yeast ccc1 mutant. Belongs to the CCC1 family.
