NuRD-mediated gene repression in mouse embryonic stem cells

ABSTRACT: To obtain a global view of NuRD-mediated transcriptional regulation, gene expression profiles of wild-type and Mbd3-null ES cells were compared by microarray analysis. In the absence of Mbd3, which encodes a core structural component of NuRD, the complex does not form and embryonic development stalls at the implantation stage.

Pluripotent cells possess the ability to differentiate into any cell type. Commitment to differentiate into specific lineages requires strict control of gene expression to coordinate the downregulation of lineage inappropriate genes while enabling the expression of lineage-specific genes. The nucleosome remodelling and deacetylation complex (NuRD) is required for lineage commitment of pluripotent cells; however, the mechanism through which it exerts this effect has not been defined. Here, we sho ...[more]

Zic2, an enhancer-binding factor required for embryonic stem cell specification

Project description:The Zinc finger protein of the cerebellum 2 (Zic2) is one of the vertebrate homologs of the Drosophila pair-rule gene odd-paired (opa). Our molecular and biochemical studies have demonstrated that Zic2 to preferentially bind to transcriptional enhancers and functions as a cofactor that interacts with the NuRD complex in ES cells. Detailed genome-wide studies demonstrate that Zic2 function with Mbd3/NuRD in regulating the chromatin state and transcriptional output of genes linked to differentiation. Zic2 is dispensable for the selfrenewal of ES cells but is required for proper differentiation, similar to what has been previously reported for Mbd3/NuRD. Our study identifies Zic2 as a key factor in the execution of the pluripotency program with Mbd3/NuRD in ES cells. ChIP-seq of Zic2, Chd4, Mbd3 and Zic3 in mES cells. ChIP-seq of H3K27me3, H3K27ac, H3K4me3, H3K4me1 and PolII in mES cells after Zic2 shRNA and non-targeting shRNA. RNA-seq of mES cells after Zic2, Zic3, Mbd3 and Mta2 shRNA and non-targeting shRNA.

Stoichiometry of MBD2 vs. MBD3-NuRD

Project description:To obtain a comprehensive and quantitative view on MBD2 vs MBD3-NuRD complex stoichiometry, we performed biotin co-immunoprecipitations in Mbd3 KO ES cells expressing either biotin-tagged MBD2a or MBD3a and identified known NuRD complex members using label-free mass spectrometry (Supplementary Fig. 8b-c). We then calculated the intensity-based absolute quantification (iBAQ) values of the most predominant and statistically significant MBD-interacting proteins in both cell lines, which can be used to estimate the relative abundance. While we observe very similar complex composition between MBD2a-NuRD and MBD3a-NuRD, peptides shared between SALL1-4 proteins show a preferred interaction with the MBD2a-NuRD complex.

Dissecting the roles of MBD2 isoforms and domains in regulating NuRD complex func-tion during cellular differentiation

Project description:The Nucleosome Remodeling and Deacetylation (NuRD) complex is a crucial regulator of cellular differentiation. Two members of the Methyl-CpG-binding domain (MBD) protein family, MBD2 and MBD3, are known to be integral, but mutually exclusive subunits of the NuRD complex. Several MBD2 and MBD3 isoforms are present in mammalian cells, resulting in distinct MBD-NuRD complexes. Whether these different complexes serve distinct functional activities during differentiation is not fully explored. Based on the essential role of MBD3 in lineage commitment, we systematically investigated a diverse set of MBD2 and MBD3 variants for their potential to rescue the differentiation block observed for mouse embryonic stem cells (ESCs) lacking MBD3. While MBD3 is indeed crucial for ESC differentiation to neuronal cells, it functions independently of its MBD domain. We further identify that MBD2 isoforms can replace MBD3 during lineage commitment, however with different potential. Full-length MBD2a only partially rescues the differentiation block, while MBD2b, an isoform lacking an N-terminal GR-rich repeat, fully rescues the Mbd3 KO phenotype. In case of MBD2a, we further show that removing the methylated DNA binding capacity or the GR-rich repeat enables full redundancy to MBD3, highlighting the synergistic requirements for these domains in diversifying NuRD complex function.

¬¬ZMYND8 co-localizes with NuRD on target genes and regulates poly-ADP-ribose dependent recruitment of GATAD2A/NuRD to sites of DNA damage

Project description:The NuRD complex is generally thought to repress transcription at both hyper- and hypomethylated regions in the genome. In addition, the complex is involved in the DNA damage response. Here, we show that ZMYND8 bridges NuRD to a number of putative DNA-binding zinc finger proteins. The ZMYND8 MYND domain directly interacts with PPPLΦ motifs in the NuRD subunit GATAD2A. Furthermore, GATAD2A and GATAD2B exclusively form homodimers and they thus define mutually exclusive NuRD subcomplexes. ZMYND8 and MBD3 share a large number of genome-wide binding sites, mostly active promoters and enhancers. Depletion of ZMYND8 does not affect NuRD occupancy genome-wide and expression of NuRD/ZMYND8 target genes in steady-state asynchronous cells. However, ZMYND8 facilitates immediate recruitment of GATAD2A/NuRD to induced sites of DNA damage in a PAR-dependent manner. These results thus show that a specific substoichiometric interaction with a NuRD subunit paralogue provides unique functionality to a distinct NuRD subcomplex.

An ES cell–specific NuRD complex functions through interaction with Wdr5

Project description:The Nucleosome Remodeling and Deacetylase (NuRD) complex is a chromatin regulatory complex that functions as a transcriptional co-repressor in metazoans. The NuRD subunit Mbd3 is essential for targeting and assembly of a functional NuRD complex as well as embryonic stem cell (ESC) pluripotency. Three Mbd3 isoforms (Mbd3a, Mbd3b, and Mbd3c) are expressed in mouse. Here, we find that the Mbd3c isoform contains a unique 50–amino acid N-terminal region that is necessary for Mbd3c to specifically interact with the histone H3 binding protein Wdr5. Domain analyses of Wdr5 reveal that the Wdr5 H3K4/MLL binding pocket is required for interaction with Mbd3c. We find that while Mbd3c KO ESCs differentiate normally, Mbd3c is redundant with the Mbd3a and Mbd3b isoforms in regulation of gene expression and ESC pluripotency, with the unique Mbd3c N-terminus required for this redundancy. Together, our data characterize a novel NuRD complex variant that functions specifically in ESCs
