(A) ChIP analysis of TAP-tagged Rad6 presence at ADH1, PMA1 and YEF3 coding regions (5' & 3') in WT or mog1Δ strains. Bar charts indicate the mean and standard deviation for at least three independent experiments. Significance of the differences was obtained using Student´s t-test (*, P value = 0.01-0.05; **, P value = 0.001-0.01, ***, P value = 0.0001-0.001, ****, P value <0.0001). (B), (C) and (D) Bre1-TAP, Rtf1-TAP and Rpb3 respectively, were analyzed as described in (A). (E) Bar charts showing the relative chromatin occupancy to 5'ORFs (left panel) or 3'ORFs (right panel) of each factor relative to Rpb3 occupancy at these gene positions.
