TranscriptomicsRole of Histone Ubiquitylation and Deubiquitylation as Determined by the Analysis of an HTB1_K123R S. cerevisiae Strain
In Saccharomyces cerevisiae histone H2B is ubiquitylated at lysine 123. The SAGA complex component, Ubp8, is one of two proteases that remove this ubiquitin moiety. We analyzed gene expression in a strain containing a variant of histone H2B with lysine 123 converted to arginine to address the mechan...

TranscriptomicsThe role of PCNA ubiquitylation during unperturbed genome replication in S.pombe
To establish if PCNA ubiquitylation affects the DNA replication kinetics of specific loci, we compared rates of DNA replication across the genome between rad18+ and rad18-delta cells using the BrdU-IP sequencing method. We mapped BrdU-incorporation at 300-bp resolution and subsequent informatics an...

TranscriptomicsdKDM2 couples histone H2A ubiquitylation to histone H3 demethylation during Polycomb group silencing.
Transcription regulation involves enzyme-mediated changes in chromatin structure. Here, we describe a novel mode of histone crosstalk during gene silencing, in which histone H2A monoubiquitylation is coupled to the removal of histone H3 Lys 36 dimethylation (H3K36me2). This pathway was uncovered thr...

ProteomicsHuwe1-mediated ubiquitylation of Dvl defines a novel negative feedback loop in the Wnt signaling pathway
Wnt signaling plays a central role in development, adult tissue homeostasis and cancer. Several steps in the canonical Wnt/b-catenin signaling cascade are regulated by ubiquitylation, a protein modification that influences the stability, subcellular localization or protein-protein interactions of ta...

TranscriptomicsHistone H2B ubiquitylation and H3 lysine 4 methylation prevent ectopic silencing of euchromatic loci important for the cellular response to heat
In Saccharomyces cerevisiae, ubiquitylation of histone H2B signals methylation of histone H3 at lysine residues 4 (K4) and 79. These modifications occur at active genes but are believed to stabilize silent chromatin by limiting movement of silencing proteins away from heterochromatin domains. In the...

ProteomicsGlobal, site-resolved analysis of ubiquitylation occupancy and turnover rate reveals systems properties
Ubiquitylation regulates most proteins and biological processes in a eukaryotic cell. However, the site-specific occupancy (stoichiometry) and turnover rate of ubiquitylation have not been quantified. Here we present an integrated picture of the global ubiquitylation site occupancy and half-life. Ub...

TranscriptomicsGenome-Wide Microarray Analysis of Histone H2B Ubiquitylation mutant strains of Tetrahymena thermophila
Microarray analyses were performed to compare the gene expression profiles of wild-type and several mutant strains of the ciliated protozoan Tetrahymena thermophila. Elimination of H3K4 methylation (hht2-K4Q) and knockout of either of the ubiquitylation enzymes (delta-UBC2 and delta-BRE1) affects a ...
