Project description:Cells rely on a diverse repertoire of genes for maintaining homeostasis, but the transcriptional networks underlying their expression remain poorly understood. The MOF acetyltransferase-containing Non-Specific Lethal (NSL) complex is a broad transcription regulator. It is essential in Drosophila and haploinsufficiency of the human KANSL1 subunit results in the Koolen-de Vries syndrome. Here, we perform a genome-wide RNAi screen and identify the BET protein BRD4 as evolutionary conserved co-factor of the NSL complex. Using Drosophila and mouse embryonic stem cells, we characterise a recruitment hierarchy, where NSL-deposited histone acetylation induces BRD4 recruitment for transcription of constitutively active genes. Transcriptome analyses in Koolen-de Vries patient-derived fibroblasts reveals perturbations with a cellular homeostasis signature that are evoked by the NSL complex/BRD4-axis. We propose that BRD4 represents a conserved bridge between the NSL complex and transcription activation and provide a new perspective in the understanding of their functions in healthy and diseased states.

Project description:We assessed the genome-wide binding of the histone acetylase MOF and members of its two associated complexes, the male-specific lethal and the non-specific lethal complex (MSL, NSL). We generated ChIP-seq profiles for MOF, MSL1, MSL2, KANSL3, and MCRS1 from mouse embryonic stem cells and neuronal progenitor cells. By using two replicates per sample and stringent filtering criteria, we identify five basic groups of genome regions where the proteins show either mutual or exclusive binding. We find that the NSL complex members (KANSL3, MCRS1) target the TSSs of broadly expressed genes with housekeeping functions in both cell types. MOF and particularly the MSL complex target a subset of these NSL-complex-targets, too. In addition, we find several thousand TSS-distal binding sites, particularly in ESCs, where KANSL3, MSL2 and MCRS1 show strong enrichments for annotated ESC enhancers. The vast majority of the binding to these ESC distal regulatory elements is lost in NPCs. Finally, we identify mostly intronic and intergenic regions with predominant MSL2 enrichments without the presence of its known interactors. These binding sites do not overlap with ESC marks of active chromatin (e.g. DNase hypersensitivity sites), but the they increase in number upon differentiation and we detect a strong signature of the (CAGA)n motif. Our study provides the first comprehensive analysis of MOF in the context of its two complexes in the mouse and reveals shared as well as distinct and dynamic functions for gene regulation and pluripotency. ChIP-seq of MOF and members of its associated complexes (MSL complex: MSL1, MSL2; NSL complex: KANSL3, MCRS1) in male mouse embryonic stem cells and neuronal progenitor cells derived from them.

Project description:The human males absent on the first (MOF)-containing non-specific lethal (NSL) histone acetyltransferase complex consists of 9 subunits can acetylate histone H4K16, H4K5 and H4K8. It has been known that this complex shares WDR5 subunit with the MLL/SET histone methyltransferases, suggesting that NSL complex is essential for the multiple transcriptional regulation mechanisms. However, there are few reports on the function of NSL HAT in genome, It is necessary to clarify the details and specificity of histone H4 acetylation cooperates with H3K4 methylation to regulate gene transcription. In this work, Our results show that The NSL complex plays a critical role in regulating multiple histone modifications by using the CRISPR/Cas9 NSL3-KO 293T cell line and ChIP-Seq approach. The global levels of highly enriched H4K16ac, H4K5ac, H3K4me2 and H3K4me3 at TSSs (TSS ± 3 kb region) are inhibited by NSL3-KO. NSL3-KO seemed to have little effect on the enhancer mark H3K27ac and repressor mark H3K27me3, but H3K4me1 was greatly affected by NSL3-KO. Moreover, the NSL complex govern gene transcription and identified genes by a coordinative mode of H4K16ac and H3K4me2/me3. What’s more, De novo motif analysis of MOF and NSL3 targets indicated that the NSL complex forms a gene regulatory network with multiple transcription factors by regulating their genes expression or cooperating with some factors through binding to specific motif.

Project description:The human males absent on the first (MOF)-containing non-specific lethal (NSL) histone acetyltransferase complex consists of 9 subunits can acetylate histone H4K16, H4K5 and H4K8. NSL complex is essential for the multiple transcriptional regulation mechanisms. In this work, mRNA profiles of WT and NSL3 knockout 293T cells were generated by deep sequencing, in triplicate. qRT–PCR validation was performed using SYBR Green assays. we identified more than 100 genes as NSL complex transcriptional targets, including several transcription factors (TFs), such as Yin Yang 1 (YY1) which are mainly involved in cell proliferation, biological adhesion, and metabolic processes. the NSL complex regulates gene expression by forming a gene regulatory network with multiple TFs. It is conceivable that the NSL complex participates in the regulation of a variety of biological functions in cells.

Project description:The MOF-containing NSL complex binds to many but not all promoters of active genes and potentially contributes to their proper gene expression. It is currently unknown what determines whether an active gene is bound or not. Here, we provide evidence that the NSL complex primarily targets active promoters of most housekeeping genes. There, it co-localizes with the chromatin remodeler NURF and the histone methyltransferase Trithorax. Moreover, despite binding to most housekeeping genes, the NSL complex regulates only a subset of them, which are depleted for certain insulator binding-proteins and enriched for the core promoter motif “Ohler 5”. We suggest that the combination of general chromatin factors and core promoter motifs is predictive for whether a housekeeping gene is transcriptionally regulated by the NSL complex.
