Number of promoters. a Binding sites of Hsf1, as determined by ChIP-on chip, were mapped to display their distance from the start codon of the closest genes. Number of promoters for each distance is represented in this histogram. The X-axis represents the binding distance from the start codon and the Y-axis denotes the number of genes. b Number of binding sites of Hsf1 seen on the inside, promoter and downstream regions of genes. Common genes are represented in the overlapping regions of the diagram. c Comparison of number of binding sites in wildtype and iron deprived cells in inside, promoter and downstream regions
