Figure 7. BRD4 isoforms have different binding affinities to histones.

Figure 7

(A) MODified Histone Peptide Array of whole cell lysate from HEK293 cells transiently transfected with FLAG-tagged BRD4-LF, FLAG-tagged BRD4-SF or V5-tagged point mutations of both isoforms. The arrays were visualized using ECL plus western blot detecting reagent. (B) The specificity factor calculated as the ratio of average intensity of all spots containing the mark divided by average intensity of all spots not containing the mark. The graph shows the 10 modifications with the greatest specificity factors.
