Histone lysine acylations play an important role in regulation of gene transcription in chromatin. Unlike histone acetyl-lysine, molecular recognition of recently identified crotonyl-lysine mark is much less understood. Here, we report that the YEATS domain of AF9 preferentially binds crotonyl-lysine over acetyl-lysine in histone H3. NMR structural analysis reveals that crotonyl-lysine of histone H3 lysine 18 is engulfed deep into an aromatic cage of the YEATS domain where carbonyl oxygen of crotonyl-lysine forms a hydrogen bond to backbone amide of protein residue Tyr78. The crotonyl-lysine through its unique electron-rich double bond side chain engages π–π aromatic stacking and extended hydrophobic/aromatic interactions with the YEATS domain as compared to acetyl-lysine. Our mutational analysis confirmed key protein residues Phe59 and Tyr78 for crotonyl-lysine recognition. Importantly, our findings present a new structural mechanism of protein-protein interactions mediated by histone lysine crotonylation, and show how the cells interpret acyl-lysine marks in different biological contexts. Zhang et al. report AF9 YEATS domain preferential recognition of crotonyl-lysine over acetyl-lysine in histone H3 via a unique π–π–π stacking structural mechanism. This study presents a new molecular mechanism underlying the role of histone lysine crotonylation in regulation of gene transcription in chromatin.
