Abstract
Increasing data suggested that histone methylation modification plays an important role in regulating biosynthesis of secondary metabolites (SMs). Monascus spp. have been applied to produce hypolipidemic drug lovastatin (also called monacolin K, MK) and edible Monascus-type azaphilone pigments (MonAzPs). However, little is known about how histone methylation regulates MK and MonAzPs. In this study, we constructed H3K9 methyltransferase deletion strain ΔMpDot1 and H4K20 methyltransferase deletion strain ΔMpSet9 using Monascus pilosus MS-1 as the parent. The result showed that deletion of MpDot1 reduced the production of MK and MonAzPs, and deletion of MpSet9 increased MonAzPs production. Real-time quantitative PCR (RT-qPCR) showed inactivation of mpdot1 and mpset9 disturbed the expression of genes responsible for the biosynthesis of MK and MonAzPs. Western blot suggested that deletion of MpDot1 reduced H3K79me and H4K16ac, and deletion of MpSet9 decreased H4K20me3 and increased H4pan acetylation. Chromatin immunoprecipitation coupled with quantitative PCR (ChIP-qPCR) showed ΔMpDot1 strain and ΔMpSet9 strain reduced the enrichment of H3K79me2 and H4K20me3 in the promoter regions of key genes for MK and MonAzPs biosynthesis, respectively. These results suggested that MpDot1 and MpSet9 affected the synthesis of SMs by regulating gene transcription and histone crosstalk, providing alternative approach for regulation of lovastatin and MonAzPs.

Abstract
The effects of phosphorylation of histone H3 at serine 10 have been studied in the context of other posttranslational modifications such as lysine methylation. We set out to investigate the impact of phosphoserine-10 on arginine-8 methylation. We performed methylation reactions using peptides based on histone H3 that contain a phosphorylated serine and compared the extent of arginine methylation with unmodified peptides. Results obtained via fluorography indicate that peptides containing a phosphorylated serine-10 inhibit deposition of methyl groups to arginine-8 residues. To further explore the effects of phosphoserine on neighboring arginine residues, we physically characterized the non-covalent interactions between histone H3 phosphoserine-10 and arginine-8 using 31P NMR spectroscopy. A salt bridge was detected between the negatively charged phosphoserine-10 and the positively charged unmodified arginine-8 residue. This salt bridge was not detected when arginine-8 was symmetrically dimethylated. Finally, molecular simulations not only confirm the presence of a salt bridge but also identify a subset of electrostatic interactions present when arginine is replaced with alanine. Taken together, our work suggests that the negatively charged phosphoserine maximizes its interactions. By limiting its exposure and creating new contacts with neighboring residues, it will inhibit deposition of neighboring methyl groups, not through steric hindrance, but by forming intrapeptide interactions that may mask substrate recognition. Our work provides a mechanistic framework for understanding the role of phosphoserine on nearby amino acid residues and arginine methylation.

Abstract
Yeast Hsl7 is recognized as a homolog of human arginine methyltransferase 5 (PRMT5) and shows type II PRMT activity by forming symmetric dimethylarginine residues on histones. Previously, we reported that Hsl7 is responsible for in vivo symmetric dimethylation on histone H4 arginine 3 (H4R3me2s) in a transcriptionally repressed state, possibly in association with histone deacetylation by Rpd3. Here, we investigated the function of Hsl7 during cell cycle progression. We found that the accumulation of Hsl7-mediated H4R3me2s is maintained by the histone deacetylase Rpd3 during transcriptional repression and that the low level of H4R3me2s is required for proper asymmetric cell growth during cell division. Our results suggest that the hypoacetylated state of histones is connected to the function of Hsl7 in regulating properly polarized cell growth during cell division and provide new insight into the epigenetic modifications that are important for cell cycle morphogenesis checkpoint control based on the repressive histone crosstalk between symmetric arginine methylation of H4 and histone deacetylation.

Abstract
Monoubiquitylation of histone H2B (H2Bub1), catalyzed by the heterodimeric ubiquitin ligase complex RNF20/40, regulates multiple molecular and biological processes. The addition of a large ubiquitin moiety to the small H2B is believed to change the biochemical features of the chromatin. H2B monoubiquitylation alters nucleosome stability, nucleosome reassembly and higher order compaction of the chromatin. While these effects explain some of the direct roles of H2Bub1, there is growing evidence that H2Bub1 can also regulate multiple DNA-templated processes indirectly, by recruitment of specific factors ("readers") to the chromatin. H2Bub1 readers mediate much of the effect of H2Bub1 on histone crosstalk, transcriptional outcome and probably other chromatin-related activities. Here we summarize the current knowledge about H2Bub1-specific readers and their role in various biological processes. This article is part of a Special Issue entitled: Molecular mechanisms of histone modification function.
