Project description:Investigation of the co-occurance of the ATP-dependent chromatin remodeler SMARCAD1 and the histone modification H3K9me3 in the genome of PGK12.1 XX ES cells. ChIP-seq of endogenous SMARCAD1 was carried out in control and SMARCAD1-knockdown ES cells using a double crosslinking procedure. Additionally, H3K9me3 ChIP-seq was performed in double-cross linked control PGK12.1 XX cells. Input samples and precipitates with an IgG antibody were sequenced (Illumina HiSeq1500) as controls. Antibodies used were SMARCAD1 PAB15737 (Abnova) and H3K9me3 ab8898 (abcam).

Project description:To understand the role of the SWI/SNF-like ATP-dependent chromatin remodeller SMARCAD1 in pluripotent murine embryonic stem (ES) cells we determined the genome wide binding of triple FLAG tagged SMARCAD1 in PGK12.1 XX ES cells. ChIP was carried out using an antibody against the FLAG-epitope (F1804, Sigma) in double-cross linked chromatin. As controls, input samples and ChIP of PGK12.1 XX ES cells transfected with the empty triple-flag vector were used. The precipitated DNA was subsequently sequenced on an Illumina HiSeq1500.

Project description:Maintaining the dynamic structure of chromatin is critical for regulating the cellular processes that require access to the DNA template, such as DNA damage repair, transcription, and replication. Histone chaperones and ATP-dependent chromatin remodeling factors facilitate transitions in chromatin structure by assembling and positioning nucleosomes through a variety of enzymatic activities. SMARCAD1 is a unique chromatin remodeler that combines the ATP-dependent ability to exchange histones, with the chaperone-like activity of nucleosome deposition. We have shown previously that phosphorylated SMARCAD1 exhibits reduced binding to nucleosomes. However, it is unknown how phosphorylation affects SMARCAD1’s ability to perform its various enzymatic activities. Here we use mutational analysis, activity assays, and mass spectrometry, to probe SMARCAD1 regulation and to investigate the role of its flexible N-terminal region. We show that phosphorylation affects SMARCAD1 binding to nucleosomes and DNA, as well as ATP hydrolysis and histone exchange. Conversely, we report that phosphorylation is inconsequential for histone binding and nucleosome assembly. In addition, the SMARCAD1 N-terminal region is revealed to be critical for nucleosome assembly and histone exchange. Together, this work examines the intricacies of how phosphorylation governs SMARCAD1 activity and provides insight into its complex regulation and diverse activities.Maintaining the dynamic structure of chromatin is critical for regulating the cellular processes that require access to the DNA template, such as DNA damage repair, transcription, and replication.

Project description:How intestinal epithelial cells interact with the host immune system and the microbiota and how this is regulated at the gene expression level are critical questions. Smarcad1 is one of the most conserved chromatin remodelling factors, from yeast to human, with suggested functions in gene silencing, heterochromatin maintenance and genome stability. However, its role in tissue function is poorly understood. As this factor is highly expressed in the stem- and proliferative zone in the intestinal epithelium, we explored the role of this factor in this tissue. Specific deletion of Smarcad1 in the intestinal epithelium led to colitis resistance in the dextran sodium sulphate colitis model. Intestine tissue-specific deletion of Smarcad1 resulted in notable changes in gene expression in the small intestine and colon. Absence of Smarcad1 led to changes in chromatin accessibility and significant changes in histone H3K9me3 but not H3K9me2 over many sites, including many genes that are differentially regulated upon Smarcad1 deletion. Our study demonstrates that an innate immunity response can be coordinated by a chromatin remodelling factor.

Project description:The ATP dependent chromatin remodeler SMARCAD1 and the co-repressor KAP1 (Trim28/Tif1 beta) interact directly. We wanted to understand the interplay between these two proteins in the context of chromatin; in particular at repetitive sequences. Therefore, we carried out an investigation in E14 ES cells of the genome wide binding behaviour of KAP1 and FLAG-tagged SMARCAD1; both wild-type SMARCAD1 and a catalytically inactive mutant. The E14 cells analysed were either wild-type or depleted for endogenous SMARCAD1 protein. FLAG and KAP1 ChIP was performed on double-cross linked chromatin and sequenced on an Illumina HiSeq1500 with matched input controls. A FLAG antibody precipitation was carried out on cells not expressing FLAG tagged protein as an additional control.
