GenomicsProteo-Genomic Characterization and Mapping of Nucleosomes Decoded by Brd and HP1 Proteins (Chip-Seq data)
Background: Histone post-translational modifications (PTMs) constitute a branch of epigenetic mechanisms that can control the expression of eukaryotic genes in a heritable manner. Recent studies have identified several PTM-binding proteins containing diverse specialized domains whose recognition of ...

TranscriptomicsChromatin IP of POF, HP1 and H3K9ac in S2 cells and salivary glands.
Two chromosome-targeting and gene regulatory systems are present in Drosophila melanogaster. The male X-chromosome is targeted by the male-specific lethal complex believed to mediate the two-fold up-regulation of the X-linked genes. The highly heterochromatic 4th chromosome is specifically targeted ...

TranscriptomicsIdentification of HP1 protein binding sites in Drosophila Kc cells using DamID
Heterochromatin protein HP1 is thought to play key role in chromatin structure and gene regulation. We performed a genome-wide mapping of HP1 target genes in the non-polytenic Drosophila Kc cells by using DamID. This approach is based on the ability of a chromatin protein fused to Escherichia coli D...

TranscriptomicsRNAi knock down of heterochromatin protein 1 in male and female Drosophila flies
Drosophila heterochromatin protein 1- HP1 is believed to be involved in active transcription, transcriptional gene silencing, and the formation of heterochromatin2-7. However, little is known about the function of HP1 during development. Using a Gal4-induced RNA interference system, we show that con...

GenomicsHeterochromatin remodeling by CDK12 contributes to learning in Drosophila
We describe the epigenetic profiling of the H3K9me2 and HP1a in Drosophila third instar larvae before and after CDK12 depletion by RNA interference (RNAi). Here we show that CDK12 regulates heterochromatin dynamics in Drosophila chromosomes. Depletion of CDK12 induces the increased HP1a and H3K9me2 ...

TranscriptomicsHP1, H3-K27me3, and H3-K9me3 Cut & Tag of Het (Cbx1+/+, Cbx3+/+, Cbx5+/-) and TKO (Cbx1-/-, Cbx3-/-, Cbx5-/-) bipotential mouse embryonic liver (BMEL) cells
Cut & Tag was used to localize the 3 mouse HP1 proteins (Cbx1,Cbx3,Cbx5) to the genome of BMEL (bipotential mouse embryonic liver) cells. Het BMEL cells are Cbx1+/+, Cbx3+/+, Cbx5+/- HP1-TKO (triple knock-out cells) are Cbx1-/-, Cbx3-/-, Cbx5-/-. The HP1_TKO cells were used to verify the specificity...

TranscriptomicsIdentification of SUUR protein binding sites in Drosophila Kc cells using DamID
Salivary gland polytene chromosomes of Drosophila melanogaster have a reproducible set of intercalary heterochromatin sites, characterized by late DNA replication, underreplicated DNA, breaks and frequent ectopic contacts. The SuUR mutation has been shown to suppress underreplication, and wild-type ...

TranscriptomicsHP1 is involved in regulating the global impact of DNA methylation on alternative splicing
The global impact of DNA methylation on alternative splicing is largely unknown. Using a genome-wide approach in wild-type and methylation-deficient embryonic stem cells, we found that DNA methylation can act both as an enhancer and as a silencer of splicing, and affects the splicing of more than 20...
