(A) Peptide pulldowns of ENL, AF9, YEATS2, and GAS41 with the indicated acylated histone peptides with or without 1, 7, 11, and 24. Unmodified histone peptides were used as negative controls to the acylated peptides and DMSO as a negative control to compound treatment. (B) AlphaScreen measurement of IC50 of 1, 7, 11, and 24 in inhibition of YEATS domains binding to the corresponding acylated histone peptides as in (A). Data represent mean ± SEM, n = 4.
