Figure 4From: Basal core promoters control the equilibrium between negative cofactor 2 and preinitiation complexes in human cellsTFIIB versus NC2 binding to human promoters. (a) Genome-wide correlation of TFIIB and NC2 binding levels on promoter regions. r, Pearson's correlation. (b) Pie chart showing the overlap of high-occupancy promoters (upper 10th percentile) recovered in TFIIB and NC2 ChIP-chip samples. (c) Comparison of the frequencies of TATA and BREu consensus sequences in high-TFIIB versus high-NC2 promoters.Back to article page
