(Submitter supplied) The histone chaperone FACT occupies transcribed regions where it plays prominent roles in maintaining chromatin integrity and preserving epigenetic information. How it is targeted to transcribed regions, however, remains unclear. Proposed models for how FACT finds its way to transcriptionally active chromatin include docking on the RNA polymerase II (RNAPII) C-terminal domain (CTD), recruitment by elongation factors, recognition of modified histone tails and binding partially disassembled nucleosomes. more...

(Submitter supplied) The histone chaperone FACT and histone H2B ubiquitination (H2Bub) facilitate RNA Polymerase II passage through chromatin. It remains unknown to what extent they cooperate in vivo. Here, we used genome-wide, genetic, biochemical and microscopic approaches to dissect their interplay in the fission yeast Schizosaccharomyces pombe. We show that FACT and H2Bub repress antisense transcripts near the 5’ end and inside gene bodies, respectively. more...

(Submitter supplied) The FACT (FAcilitates Chromatin Transactions) complex is a conserved complex that maintains chromatin structure on transcriptionally active genes. Consistent with this, FACT is enriched on highly expressed genes, but how it is targeted to these regions is unknown. In vitro, FACT binds destabilized nucleosomes, supporting the hypothesis that FACT is targeted to transcribed chromatin through recognition of RNA polymerase-disrupted nucleosomes. more...

(Submitter supplied) The genetic information encoded in DNA is framed by additional layers of information, referred to as the epigenome. Epigenetic marks such as DNA methylation, histone modifications and histone variants are concentrated on specific genomic sites as means to instruct, but also sometimes as a consequence of, gene expression. How this information is maintained, notably in the face of transcription, is not understood. more...

(Submitter supplied) FACT is a histone chaperone that can destabilize or assemble nucleosomes. Acetylation of histone H3-K56 weakens a histone:DNA contact that is central to FACT activity, suggesting that this modification could affect FACT functions. We tested this by asking how mutations of H3-K56 and FACT affect nucleosome structure, chromatin integrity, and transcription output. Mimics of unacetylated or permanently acetylated H3-K56 had different effects on FACT in vitro and in vivo as expected, but H3-K56 and FACT mutations caused surprisingly similar changes in transcription of individual genes. more...

(Submitter supplied) 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. more...

(Submitter supplied) The FACT complex and Spt6 are conserved histone chaperones that are recruited to the open reading frames of transcribed genes. In this study, we provide evidence that FACT interaction with acetylated H3 tail is important for its localization to the coding sequences. Pol II CTD kinase Kin28 additionally stimulates FACT recruitment to a subset of genes. Pol II occupancies in the 5’ ends of transcribed genes are greatly reduced on depleting FACT, whereas reduced occupancies at the 3’ ends were observed upon Spt6 depletion indicating that these factors modulate Pol II progression through distinct regions of transcribed coding sequences. more...
