    ..At the GAL1 promoter, Cyc8-Tup1 facilitates recruitment of SAGA (Spt-Ada-Gcn5-acetyltranferase) via Cti6, a PHD domain protein that physically links the Cyc8-Tup1 and SAGA complexes...
  67. Govind C, Zhang F, Qiu H, Hofmeyer K, Hinnebusch A. Gcn5 promotes acetylation, eviction, and methylation of nucleosomes in transcribed coding regions. Mol Cell. 2007;25:31-42 pubmed
    ..Gcn5p also enhances H3-K4 trimethylation in the ARG1 ORF and bulk histones. Thus, Gcn5p, most likely in SAGA, stimulates modification and eviction of nucleosomes in transcribed coding sequences and promotes Pol II elongation. ..
