Figure 6From: Global transcriptional responses of fission and budding yeast to changes in copper and iron levels: a comparative studyAn updated model for transcriptional regulation by Cuf1p and Fep1p. (a) Previously proposed mechanism for Cuf1p-dependent repression of iron uptake genes [43]. (b) Revised model of Cuf1p and Fep1p regulation in S. pombe, including novel regulatory targets.
