Project description:By using of paired-end sequencing technology, we report the high-throughput profiling of Jhd2 targeting in S. cerevisiae. We obtained more than 1.8E+7 Illumina reads and generated 1.1E+7 mapped reads from Jhd2-ChIP DNA . Sequence reads for Jhd2-ChIP and Input DNA were mapped to yeast genome by using the BWA (Burrows Wheeler Aligner), SAMtools (Sequence Alignment Map) programs and followed by SICER (Spatial clustering for Identification of ChIP-Enriched Regions) program to obtain the Significant peaks. We found that the overall Jhd2 distribution across the gene body of targets is fairly correlated to the levels of H3K4 di- and tri-methylation, which are enriched at 5’ through 3’ of ORF regions. These observations demonstrate that the Jhd2, a histone H3K4 demethylase, is linked to gene transcription by locating mainly at the coding regions to balance the H3K4me of its target genes at steady state. Furthermore, we observed that Jhd2 are significantly enriched at several specific chromosomal loci including telomeres, centromeres, silent HM loci, LTR-tRNAs, and rDNA arrays. Our study demonstrated that Jhd2, H3K4-demethylase, plays a dynamic role as a chromatin insulator to define boundary regions between euchromatin and heterochromatin by association with specific chromatin loci in the yeast genome.

Project description:Histone H3K4 methylation is connected to gene transcription from yeast to humans, but its mechanistic role in transcription and chromatin dynamics remains poorly understood. Here, we investigated the functions for Set1 and Jhd2, the sole H3K4 methyltransferase and H3K4 demethylase, respectively, in S. cerevisiae. Our data show that Set1 and Jhd2 predominantly co-regulate transcription. We find combined activities of Set1 and Jhd2 via H3K4 methylation contribute to positive or negative transcriptional regulation at shared target genes. Providing mechanistic insights, our data reveal that Set1 and Jhd2 together control nucleosomal occupancy during transcriptional co-regulation. Moreover, we find a remarkable genome-wide co-regulation of nucleosome and chromatin structure by Set1 and Jhd2 at different groups of transcriptionally active or inactive genes and at different regions within yeast genes. Overall, our study prompts a model wherein combined actions of Set1 and Jhd2 via H3K4 methylationâdemethylation control chromatin dynamics during various facets of transcriptional regulation. Genome-wide nucleosome maps were generated from three different yeast strains representing wild type control, set1 null and jhd2 null mutants. Three independent biological samples were grown for each strain, nucleosomes were prepared by micrococcal nuclease digestion, libraries were prepared, mononculeosomal DNA was isolated, sequenced, and analyzed separately.

Genome-wide nucleosome maps were generated from three different yeast strains representing no tag control, 8V5-Set1 and Jhd2-12V5. Cells were cross-linked with formaldehyde, spheroplasted, nuclei were isolated and chromatin was prepared using micrococcal nuclease digestion, chromatin immunoprecipitation was performed using an epitope-tag specific antibody, libraries were prepared from ChIP and input DNA, sequenced, and analyzed separately.
