Gene expression profiling on heads of Drosophila chromodomain helicase DNA binding protein 1 (CHD1) deletion mutants

Project description:CHD1 is a conserved ATP-dependent chromatin remodeling factor with roles in transcriptional regulation and chromatin assembly. Here we show that deletion of Chd1 causes multiple behavioral and metabolic defects. In particular, it diminishes food-intake and results in shortened lifespan of mutant flies. These phenotypes can be rescued by brain-specific expression of Chd1 via the elav promoter. Consistently, neuron-specific expression of Chd1 rescues the wide-spread transcriptional dysregulation observed in the absence of CHD1.

CHD1 in yeast is recruited by transcription elongation factors and maintains H3K4me3/H3K36me3 domains at actively transcribed and spliced genes

Project description:Chd1 is a conserved ATP-dependent chromatin remodeler that maintains the nucleosomal structure of chromatin, but the determinants of its specificity and its impact on gene expression are not well defined. To identify the determinants of Chd1 binding specificity in the yeast genome, we investigated Chd1 occupancy in mutants of several candidate factors. We found that several components of the PAF1 transcription elongation complex contribute to Chd1 recruitment to highly transcribed genes, and identified Spt4 as a factor that appears to negatively modulate Chd1 binding to chromatin. We discovered that CHD1 loss alters H3K4me3 and H3K36me3 patterns throughout the yeast genome. Interestingly, the aberrant histone H3 methylation patterns were predominantly observed within 1 kb from the transcription start site, where both histone H3 methylation marks co-occur. A reciprocal change between the two marks was obvious in the absence of Chd1, suggesting a role for CHD1 in establishing or maintaining the boundaries of these largely mutually exclusive histone marks. Strikingly, intron-containing genes were most susceptible to CHD1 loss, and exhibited a high degree of histone H3 methylation changes. Intron retention was significantly lower in the absence of CHD1, suggesting that CHD1 function as a chromatin remodeler could indirectly affect RNA splicing. This SuperSeries is composed of the SubSeries listed below.

A Key Role for Chd1 in Histone H3 Dynamics at the 3' Ends of Long Genes in Yeast (H3K4me3 or H3K36me3 to input)

Project description:Chd proteins are ATP-dependent chromatin remodeling enzymes implicated in biological functions from transcriptional elongation to control of pluripotency. Here, we examine roles of Chd1 in replication- independent dynamics of histone H3 in yeast. Using genome-wide ChIP on chip analysis, we find that Chd1 influences histone turnover at the 5M-bM-^@M-^Y and 3M-bM-^@M-^Y ends of genes, accelerating H3 replacement at the 5M-bM-^@M-^Y ends of genes while protecting the 3M-bM-^@M-^Y ends of genes from excessive H3 turnover. Although consistent with a direct role for Chd1 in exchange, these results may indicate that Chd1 stabilizes nucleosomes perturbed by transcription. Curiously, we observe a strong effect of gene length on Chd1M-bM-^@M-^Ys effects on H3 turnover. Finally, we show that Chd1 also affects histone H3K4 and H3K36 methylation patterns over genes, likely as a consequence of its effects on histone replacement. In control experiments, we measure effects of deletion of CHD1 on RNA polymerase II distribution across the genome and on gene expression. We also examine the effect of deleting the TOP1 gene, alone and in combination with deletion of CHD1, on histone replacement. Taken together, our results emphasize a role for Chd1 in histone replacement in both budding yeast and Drosophila, and surprisingly show that the major effects of Chd1 on turnover occur at the 3M-bM-^@M-^Y ends of genes.
