|a The Zrt/Irt-like protein (ZIP) family generally contributes to metal homeostasis by regulating cation transport into the cytoplasm. Most ZIP members have a long variable loop between transmembrane domains III and IV, and these loops are predicted to be located in the cytoplasm. The loops contain a histidine-rich domain (HRD) postulated to serve as a metal ion binding site; however, its role has not yet been determined. We previously determined that deletion of the HRD did not affect the Ni tolerance ability of TjZNT1-a ZIP transporter that confers high Ni tolerance to yeast. In this study, we investigated the effect of HRD deletion on the ion transport ability of TjZNT1. The deletion of HRD increased the specificity for Zn2+, but not for Cd2+. In addition, we confirmed subcellular localizations of TjZNT1 and HRD-deleted mutants by green fluorescence protein (GFP)-fused proteins, indicating that the deletion of HRD did not affect the localization of TjZNT1. From these results, we propose that the HRD could be involved in the ion specificity of TjZNT1
