Figure 3

Binding profiles of transcription factors (TFs) correlate with X-element positions. Subtelomeric-binding profiles are shown for factors found to enriched at X elements in Figure 2. The densities of TF binding and X elements present on the microarrays are represented as heat maps. Binding conditions other than rich medium are marked with colored dots as in Figure 2. With the exception of Phd1p, all factors had maximal binding 5–7 kb from telomeres, matching the position of X element enrichment. Pearson's correlation coefficients (ρ) comparing each binding profile to the positions of X elements are shown at the right.
