Vacuolar iron transporter involved in the transfer of iron ions from the cytosol to the vacuole for intracellular iron storage (PubMed:30742036). Can transport cobalt ions from the cytosol to the vacuole (PubMed:30742036). Transport of iron ions is inhibited by zinc ions. Homodimer (PubMed:30742036). The dimeric interaction is mediated by both the transmembrane domains (TMDs) and the cytoplasmic metal binding domain (MBD) (PubMed:30742036). The cytoplasmic metal binding domain (MBD) is located between transmembrane 2 (TM2) and transmembrane 3 (TM3). Can mediate sequestration of iron ions into vacuoles when expressed in the yeast ccc1 mutant. Belongs to the CCC1 family.
