The Taf14 YEATS domain is a reader of histone crotonylation.

ABSTRACT: The discovery of new histone modifications is unfolding at startling rates; however, the identification of effectors capable of interpreting these modifications has lagged behind. Here we report the YEATS domain as an effective reader of histone lysine crotonylation, an epigenetic signature associated with active transcription. We show that the Taf14 YEATS domain engages crotonyllysine via a unique ?-?-?-stacking mechanism and that other YEATS domains have crotonyllysine-binding activity.

Here we report the YEATS domain as an effective reader of histone lysine crotonylation, an epigenetic signature associated with active transcription.

Molecular Coupling of Histone Crotonylation and Active Transcription by AF9 YEATS Domain.

Project description:Recognition of histone covalent modifications by chromatin-binding protein modules ("readers") constitutes a major mechanism for epigenetic regulation, typified by bromodomains that bind acetyllysine. Non-acetyl histone lysine acylations (e.g., crotonylation, butyrylation, propionylation) have been recently identified, but readers that prefer these acylations have not been characterized. Here we report that the AF9 YEATS domain displays selectively higher binding affinity for crotonyllysine over acetyllysine. Structural studies revealed an extended aromatic sandwiching cage with crotonyl specificity arising from π-aromatic and hydrophobic interactions between crotonyl and aromatic rings. These features are conserved among the YEATS, but not the bromodomains. Using a cell-based model, we showed that AF9 co-localizes with crotonylated histone H3 and positively regulates gene expression in a YEATS domain-dependent manner. Our studies define the evolutionarily conserved YEATS domain as a family of crotonyllysine readers and specifically demonstrate that the YEATS domain of AF9 directly links histone crotonylation to active transcription.

Recognition of Histone Crotonylation by Taf14 Links Metabolic State to Gene Expression.

Project description:Metabolic signaling to chromatin often underlies how adaptive transcriptional responses are controlled. While intermediary metabolites serve as co-factors for histone-modifying enzymes during metabolic flux, how these modifications contribute to transcriptional responses is poorly understood. Here, we utilize the highly synchronized yeast metabolic cycle (YMC) and find that fatty acid β-oxidation genes are periodically expressed coincident with the β-oxidation byproduct histone crotonylation. Specifically, we found that H3K9 crotonylation peaks when H3K9 acetylation declines and energy resources become limited. During this metabolic state, pro-growth gene expression is dampened; however, mutation of the Taf14 YEATS domain, a H3K9 crotonylation reader, results in de-repression of these genes. Conversely, exogenous addition of crotonic acid results in increased histone crotonylation, constitutive repression of pro-growth genes, and disrupted YMC oscillations. Together, our findings expose an unexpected link between metabolic flux and transcription and demonstrate that histone crotonylation and Taf14 participate in the repression of energy-demanding gene expression.

Identification of the YEATS domain of GAS41 as a pH-dependent reader of histone succinylation.

Project description:Lysine succinylation is a newly discovered posttranslational modification with distinctive physical properties. However, to date rarely have studies reported effectors capable of interpreting this modification on histones. Following our previous study of SIRT5 as an eraser of succinyl-lysine (Ksuc), here we identified the GAS41 YEATS domain as a reader of Ksuc on histones. Biochemical studies showed that the GAS41 YEATS domain presents significant binding affinity toward H3K122suc upon a protonated histidine residue. Furthermore, cellular studies showed that GAS41 had prominent interaction with H3K122suc on histones and also demonstrated the coenrichment of GAS41 and H3K122suc on the p21 promoter. To investigate the binding mechanism, we solved the crystal structure of the YEATS domain of Yaf9, the GAS41 homolog, in complex with an H3K122suc peptide that demonstrated the presence of a salt bridge formed when a protonated histidine residue (His39) recognizes the carboxyl terminal of the succinyl group. We also solved the apo structure of GAS41 YEATS domain, in which the conserved His43 residue superimposes well with His39 in the Yaf9 structure. Our findings identified a reader of succinyl-lysine, and the binding mechanism will provide insight into the development of specific regulators targeting GAS41.

The YEATS domain of Taf14 in Saccharomyces cerevisiae has a negative impact on cell growth.

Project description:The role of a highly conserved YEATS protein motif is explored in the context of the Taf14 protein of Saccharomyces cerevisiae. In S. cerevisiae, Taf14 is a protein physically associated with many critical multisubunit complexes including the general transcription factors TFIID and TFIIF, the chromatin remodeling complexes SWI/SNF, Ino80 and RSC, Mediator and the histone modification enzyme NuA3. Taf14 is a member of the YEATS superfamily, conserved from bacteria to eukaryotes and thought to have a transcription stimulatory activity. However, besides its ubiquitous presence and its links with transcription, little is known about Taf14's role in the nucleus. We use structure-function and mutational analysis to study the function of Taf14 and its well conserved N-terminal YEATS domain. We show here that the YEATS domain is not necessary for Taf14's association with these transcription and chromatin remodeling complexes, and that its presence in these complexes is dependent only on its C-terminal domain. Our results also indicate that Taf14's YEATS domain is not necessary for complementing the synthetic lethality between TAF14 and the general transcription factor TFIIS (encoded by DST1). Furthermore, we present evidence that the YEATS domain of Taf14 has a negative impact on cell growth: its absence enables cells to grow better than wild-type cells under stress conditions, like the microtubule destabilizing drug benomyl. Moreover, cells expressing solely the YEATS domain grow worser than cells expressing any other Taf14 construct tested, including the deletion mutant. Thus, this highly conserved domain should be considered part of a negative regulatory loop in cell growth.

AF9 YEATS domain links histone acetylation to DOT1L-mediated H3K79 methylation.

Project description:The recognition of modified histones by "reader" proteins constitutes a key mechanism regulating gene expression in the chromatin context. Compared with the great variety of readers for histone methylation, few protein modules that recognize histone acetylation are known. Here, we show that the AF9 YEATS domain binds strongly to histone H3K9 acetylation and, to a lesser extent, H3K27 and H3K18 acetylation. Crystal structural studies revealed that AF9 YEATS adopts an eight-stranded immunoglobin fold and utilizes a serine-lined aromatic "sandwiching" cage for acetyllysine readout, representing a novel recognition mechanism that is distinct from that of known acetyllysine readers. ChIP-seq experiments revealed a strong colocalization of AF9 and H3K9 acetylation genome-wide, which is important for the chromatin recruitment of the H3K79 methyltransferase DOT1L. Together, our studies identified the evolutionarily conserved YEATS domain as a novel acetyllysine-binding module and established a direct link between histone acetylation and DOT1L-mediated H3K79 methylation in transcription control.

Structural Insights into Histone Crotonyl-Lysine Recognition by the AF9 YEATS Domain.

Project description:Histone lysine acylations play an important role in the regulation of gene transcription in chromatin. Unlike histone acetyl-lysine, molecular recognition of a 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. Nuclear magnetic resonance structural analysis reveals that crotonyl-lysine of histone H3 lysine 18 is engulfed deep in an aromatic cage of the YEATS domain where the carbonyl oxygen of crotonyl-lysine forms a hydrogen bond with the backbone amide of protein residue Tyr78. The crotonyl-lysine, through its unique electron-rich double-bond side chain, engages ?-? aromatic stacking and extended hydrophobic/aromatic interactions with the YEATS domain compared with 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.

Yaf9 subunit of the NuA4 and SWR1 complexes targets histone H3K27ac through its YEATS domain.

Project description:Yaf9 is an integral part of the NuA4 acetyltransferase and the SWR1 chromatin remodeling complexes. Here, we show that Yaf9 associates with acetylated histone H3 with high preference for H3K27ac. The crystal structure of the Yaf9 YEATS domain bound to the H3K27ac peptide reveals that the sequence C-terminal to K27ac stabilizes the complex. The side chain of K27ac inserts between two aromatic residues, mutation of which abrogates the interaction in vitro and leads in vivo to phenotypes similar to YAF9 deletion, including loss of SWR1-dependent incorporation of variant histone H2A.Z. Our findings reveal the molecular basis for the recognition of H3K27ac by a YEATS reader and underscore the importance of this interaction in mediating Yaf9 function within the NuA4 and SWR1 complexes.

GAS41 promotes H2A.Z deposition through recognition of the N terminus of histone H3 by the YEATS domain.

Project description:Glioma amplified sequence 41 (GAS41), which has the Yaf9, ENL, AF9, Taf14, and Sas5 (YEATS) domain that recognizes lysine acetylation (Kac), regulates gene expression as a subunit of the SRCAP (SNF2-related CREBBP activator protein) complex that deposits histone H2A.Z at promoters in eukaryotes. The YEATS domains of the proteins AF9 and ENL recognize Kac by hydrogen bonding the aromatic cage to arginine situated just before K9ac or K27ac in the N-terminal tail of histone H3. Curiously, the YEATS domain of GAS41 binds most preferentially to the sequence that contains K14ac of H3 (H3K14ac) but lacks the corresponding arginine. Here, we biochemically and structurally elucidated the molecular mechanism by which GAS41 recognizes H3K14ac. First, stable binding of the GAS41 YEATS domain to H3K14ac required the N terminus of H3 (H3NT). Second, we revealed a pocket in the GAS41 YEATS domain responsible for the H3NT binding by crystallographic and NMR analyses. This pocket is away from the aromatic cage that recognizes Kac and is unique to GAS41 among the YEATS family. Finally, we showed that E109 of GAS41, a residue essential for the formation of the H3NT-binding pocket, was crucial for chromatin occupancy of H2A.Z and GAS41 at H2A.Z-enriched promoter regions. These data suggest that binding of GAS41 to H3NT via its YEATS domain is essential for its intracellular function.
