Previous studies have identified novel modifications in the core fold domain of histone H2B, but relatively little is known about the function of these putative histone modification sites. We have mutated core modifiable residues that are conserved in Saccharomyces cerevisiae histone H2B and characterized the effects of the mutants on yeast silencing, gene expression, and the DNA damage response. We identified three histone H2B core modifiable residues as functionally important. We find that mut ...[more]

Expression data from wild-type and H2B K37A mutant yeast histones

Project description:We identified lysine 37 of histone H2B as a novel site of histone lysine methylation in budding yeast. Microarray analysis was performed to determine global changes in gene expression upon mutation of this lysine residue to a unmodifiable form. Histones were acid-extracted from asynchronously grown yeast expressing wild-type H2B or H2B harboring a K37A mutation.

The nucleolus functions as the compartment for histone 1 H2B protein degradation

Project description:Histones are the main components in chromatin organization, and the protein levels of histones significantly affect chromatin assembly. However, how the protein levels of histones are regulated, especially whether and how histones are degraded, is largely unclear. Here, we found that histone H2B is mainly degraded through the proteasome mediated pathway, and the lysine 120 site of H2B is essential for the K48-linked polyubiquitination and protein degradation of H2B. Moreover, our results further indicated that the degradation-impaired H2BK120R mutant shows an increased nucleolus localization, and inhibition of the proteasome results in an elevated nucleolus distribution of wild-type H2B, which is similar to that of H2BK120R mutants. More importantly, our in vitro data showed that only the nucleolus fractions can ubiquitinate and degrade the purified H2B, suggesting that the nucleolus, in addition to its canonical roles in the regulation of ribosome genesis and protein translation, is likely associated with H2B protein degradation. Therefore, these findings revealed a novel mechanism for the regulation of H2B protein degradation in which a nucleolus associated proteasome pathway is involved.

Co-dependency of H2B monoubiquitination and nucleosome re-assembly on Chd1

Project description:Monoubiquitination of histone H2B on lysine 123 (H2BK123ub) is a transient histone modification considered to be essential for establishing H3K4 and H3K79 trimethylation by Set1/COMPASS and Dot1, respectively. Many of the factors such as Rad6/Bre1, the Paf1 complex, and the Bur1/Bur2 complex were identified to be required for proper histone H3K4 and H3K79 trimethylation, and were shown to function by regulating H2BK123ub levels. Here, we have identified Chd1 as a factor that is required for proper maintenance of H2B monoubiquitination levels, but not for H3K4 and H3K79 trimethylation. Loss of Chd1 results in a substantial loss of H2BK123ub levels with little to no effect on the genome-wide pattern of H3K4 and H3K79 trimethylation. Our data shows that nucleosomal occupancy is reduced in gene bodies in both CHD1 null and K123A backgrounds. We have also demonstrated that Chd1’s function in maintaining H2BK123ub levels is conserved from yeast to human. Our study provides evidence that only small levels of H2BK123ub are necessary for full levels of H3K4 and H3K79 trimethylation in vivo, and points to a role for Chd1 in positively regulating gene expression through promoting nucleosome re-assembly coupled with H2B monoubiquitination. Examination of two histone modifications in wild-type and Chd1 null yeast strains using ChIP-seq. Expression profiling in wild-type and Chd1 null yeast strains using RNA-seq.
