Binding of Med17, RNAPII, and TFIIB to sn/snoRNA and mRNA genes in WT and tail deletion yeast. Genome browser views of the Med17 ChEC-seq, RNAPII ChIP-seq, and TFIIB ChIP-chip signal in WT and tail mutant yeast at two sn/snoRNA genes (snR8 and snR49), two SAGA-dominated mRNA genes (CDC19 and FBA1), and three TFIID-dominated mRNA genes (RPN6, PMT1, and RPS5) are shown.
