ProteomicsProteomics analysis of ligated and recombinant human histones H3 and H4
A library of unmodified and differentially modified human histones H3 and H4 was prepared using native chemical ligation as described previously (Bartke et al., 2010; Nakamura et al., 2019). The modification status of histone H3 and H4 products was confirmed by LC-MS/MS.

ProteomicsControl pull-downs testing the effect of histone native chemical ligation on protein binding to di-nucleosomes
Here we examined whether histones H3 and H4 produced using native chemical ligation reaction affect protein binding to di-nucleosomes. To test this we performed a set of affinity purification pull-downs using di-nucleosomes containing the following histones H3 and H4: 1. ligated unmodified histone H...

ProteomicsMARCS: Modification Atlas for Regulation by Chromatin States
Goal of this project was the identification of chromatin interacting proteins whose binding is differentially regulated by various combinatorial chromatin modifications found in different chromatin states such as promoters, enhancers and heterochromatin. To achieve this, recombinant modified nucleos...

TranscriptomicsA Basic Domain in the Histone H2B N-terminal Tail is Important for Nucleosome Assembly by FACT
Nucleosome assembly in vivo requires assembly factors, such as histone chaperones, to bind to histones and mediate their deposition onto DNA. In yeast, the essential histone chaperone FACT (FAcilitates Chromatin Transcription) functions in nucleosome assembly and H2A-H2B deposition during transcript...

GenomicsSynthetic antagonist of a histone reader reveals and targets genes essential for inflammation
Post-translational modifications of histones determines cell lineage- or signal-specific gene expression. Depending on the type and combination of modifications, histones bind to functionally distinct effector proteins ('readers') that control gene activation or silencing. The current pharmacologic...

TranscriptomicsSpt6 regulates intragenic and antisense transcription, nucleosome positioning, and histone modifications genome-wide in fission yeast [RNA-seq]
Spt6 is a highly conserved histone chaperone that interacts directly with both RNA polymerase II and histones to regulate gene expression. To gain a comprehensive understanding of the requirements for this critical factor, we have performed genome-wide analyses of transcription, chromatin structure...

GenomicsHistone H3K4 Demethylation is Negatively Regulated by Histone H3 Acetylation in S. cerevisiae
Histone H3 lysine 4 tri-methylation (H3K4me3) is a hallmark of transcription initiation, but how H3K4me3 is demethylated during gene repression is poorly understood. Jhd2, a JmjC domain protein, was recently identified as the major H3K4me3 histone demethylase (HDM) in S. cerevisiae. While JHD2 is ...
