(Submitter supplied) The Bromo-domain and PHD-finger protein, BRPF3, forms a complex with HBO1 and regulates the initiation of DNA replication. BRPF3-dependent histone H3K14 enriched in chromatin surrounding a fraction of replication origins may play an important role in origin firing. We used microarrays to evaluate whether replication defect due to the lack of BRPF3 is associated with transcriptional changes of replication genes.

(Submitter supplied) Several MYST-family histone acetyltransferase (HAT) enzymes associate with specific ING tumor suppressor proteins. ING complexes containing the HBO1 HAT protein are the major source of histone H4 acetylation in vivo and have been shown to play critical roles in gene regulation and DNA replication. Here, we present a molecular dissection of HBO1/ING HAT complexes that unravels the protein domains required for complex assembly and function. more...

(Submitter supplied) Histone acetyltransferases (HAT) assemble into multisubunit complexes in order to target distinct lysine residues on nucleosomal histones. Here, we characterize native HAT complexes assembled by the BRPF-family of scaffold proteins. Their PHD-ZnKnuckle-PHD domain is essential for binding chromatin and restricted to unmethylated H3K4, a specificity that is reversed by the associated ING subunit. Native BRPF1 complexes can contain either MOZ/MORF or HBO1 as catalytic acetyltransferase subunit. more...

(Submitter supplied) In the conventional model of transcriptional activation, transcription factors bind to response elements and recruit co-factors, including histone acetyltransferases. Contrary to this model, we show that the histone acetyltransferase KAT7 (HBO1/MYST2) is required genome-wide for histone H3 lysine 14 acetylation (H3K14ac). Examining neural stem cells, we found that KAT7 and H3K14ac were present not only at transcribed genes, but also at inactive genes, intergenic regions and in heterochromatin. more...

KAT7 and H3K14ac were not required for the continued transcription of genes that were actively transcribed at the time of loss of KAT7, but indispensable for the activation of repressed genes.

(Submitter supplied) The occupancy states of DNA-binding nucleosomes and subnucleosome-sized proteins (e.g.  transcription factors, replication proteins, etc.) determine the chromatin accessibility landscape and provide additional regulatory context for DNA-templated processes including transcription and DNA replication. Throughout the mitotic cell division cycles, the transcriptome undergoes periodic reprogramming along with replication- and mitosis-induced global chromatin reconfiguration; however, profiling of the cell cycle-specific chromatin dynamics and understandings of its regulatory mechanisms remain limited. more...

(Submitter supplied) DNA replication is a tightly regulated process that ensures the precise duplication of the genome during cell cycle. Licensing and activation of eukaryotic replication origins are controlled primarily by chromatin. However, the chromatin features involved and the regulatory mechanism remain largely unknown. In this study, we found that H2A.Z binds Suv420H1 directly to promote H4K20me2 deposition on nucleosome both in vitro and in vivo. more...

(Submitter supplied) We used ChIP-seq technology in order to map chromatin binding sites of the HBO1 MYST complex in the RKO cell line. We obtained a significant enrichment of the HBO1 signal right after TSS regions of genes and also In the proximal promoter region, with no signal on TSS. This enrichment also correlates with gene expression level.

(Submitter supplied) Acute myeloid leukaemia (AML) is a heterogeneous disease characterised by transcriptional dysregulation resulting in a block in differentiation and increased malignant self-renewal. Various epigenetic therapies aimed at reversing these hallmarks of AML have progressed into clinical trials, with most showing modest efficacy due to an inability to effectively eradicate leukaemia stem cells (LSC). To specifically identify novel dependencies in LSC we screened a bespoke library of small hairpin RNAs (shRNAs) targeting chromatin regulators in a unique ex vivo model of LSC. more...
