Zap1 mediates this response by binding to zinc-responsive elements (ZREs) located within the promoter regions of each gene. ZRT2 has a remarkably different expression profile in response to zinc compared to ZRT1. While ZRT1 is maximally induced during zinc limitation, ZRT2 is repressed in low zinc but remains induced upon zinc supplementation. In this study, we determined the mechanism underlying this paradoxical Zap1-dependent regulation of ZRT2. We demonstrate that a nonconsensus ZRE (ZRT2 ZRE3), which overlaps with one of the ZRT2 transcriptional start sites, is essential for repression of ZRT2 in low zinc and that Zap1 binds to ZRT2 ZRE3 with a low affinity. The low-affinity ZRE is also essential for the ZRT2 expression profile. These results indicate that the unusual pattern of ZRT2 regulation among Zap1 target genes involves the antagonistic effect of Zap1 binding to a low-affinity ZRE repressor site and high-affinity ZREs required for activation."xsd:string |
