Figure 4. Bye1 association with promoters of class II genes requires H3K4me3: (A, B) Quantification of Bye1-Myc enrichment in WT and strains deleted for SET1 or SPP1 genes relative to the intergenic region by ChIP; (C) Quantification of Rpb1 enrichment in WT, set1Δ and spp1Δ strains relative to the intergenic region by ChIP.

3′ORF and mORF stand for the 3′end and middle coding regions.
