To further understand the relationship between nucleosome-space occupancy (NO) and global transcriptional activity in mammals, we acquired a set of genome-wide nucleosome distribution and transcriptome data from the mouse cerebrum and testis based on ChIP (H3)-seq and RNA-seq, respectively. We identified a nearly consistent NO patterns among three mouse tissues-cerebrum, testis, and ESCs-and found, through clustering analysis for transcriptional activation, that the NO variations among chromosomes are closely associated with distinct expression levels between house-keeping (HK) genes and tissue-specific (TS) genes. Both TS and HK genes form clusters albeit the obvious majority. This feature implies that NO patterns, i.e. nucleosome binding and clustering, are coupled with gene clustering that may be functionally and evolutionarily conserved in regulating gene expression among different cell types. © 2011 Cui et al.Citation

Conformational Regulation of the Essential Epigenetic Regulator UHRF1(2018-05) [Thesis]
Advisor: Fischle, Wolfgang
Committee members: Adamo, Antonio; Mahfouz, Magdy M.; Jaremko, LukaszUHRF1 is an essential epigenetic regulator implicated in the maintenance of DNA methylation. While its functional state has been suggested to be allosterically regulated by phosphatidylinositol 5-phosphate and dependent on purification conditions and tags coupled to the protein, the expression system might have a broader impact on UHRF1s interaction properties. We hypothesized that the translation kinetics defined by the expression host has an impact on the folding process of the protein, which ultimately affects its structure and function. To test this idea, the cDNA of UHRF1 was recoded in order to generate optimized and harmonized sequences that were expected to alter the overall translation speed. Both proteins were expressed in Escherichia coli BL21-DE3 and their interaction profiles with H3K9me3 and unmodified H3 peptides were determined by microscale thermophoresis assays. The dissociation constants were compared by ttests in order to evaluate a possible change in the interaction properties of the optimized and harmonized proteins, compared to non-optimized UHRF1 expressed in E. coli BL21-DE3. While no difference was found for the interaction of optimized UHRF1 with the H3K9me3 peptide, a significant difference was found for its interaction with the unmodified H3 peptide. Moreover, both the interactions of harmonized UHRF1 with H3K9me3 and unmodified H3 peptides were determined to change. For this reason, we concluded that translation kinetics dependent on the expression system impacts the functional state of UHRF1. To further study this phenomenon, we expressed the consensus sequence of UHRF1 in Escherichia coli BL21-Codon Plus-(DE3)-RIL, a bacterial strain that is enriched with arginine, isoleucine, and leucine tRNA isoacceptors. Differences in its interaction profile with histone peptides were found when compared with UHRF1 expressed in Escherichia coli BL21-DE3. Since the major difference between these strains is the abundance of tRNAs, we obtained further findings that support our initial hypothesis. Additionally, the interaction profiles from the consensus UHRF1 protein were determined in the presence of PI5P to get an insight into how this phosphoinositide might impact the final structure and function of UHRF1. MST measurements and limited proteolysis assays led us to the idea of a partially open conformation for the UHRF1 expressed in E. coli BL21-DE3 and E.coli Codon Plus-(DE3)-RIL. -
Conservation and Regulation of the Essential Epigenetic Regulator UHRF1 Across Vertebrata Orthologs(2020-05) [Thesis]
Advisor: Fischle, Wolfgang
Committee members: Arold, Stefan T.; Aranda, ManuelUHRF1 is a critical epigenetic regulator which serves as a molecular model for understanding the crosstalk between histone modification and DNA methylation. It is integrated in the process of DNA maintenance methylation through its histone ubiquitylation activity, ultimately functioning as a recruiter of DNA methyltransferase 1 (DNMT1). As the faithful propagation of DNA methylation patterns during cell division is a common molecular phenomenon among vertebrates, understanding the underlying conserved mechanism of UHRF1 for executing such a key process is important. Here, I present a broad-range evolutionary comparison of UHRF1 binding behavior and enzymatic activity of six species spanning across the vertebrata subphylum. According to their distinct binding modes to differentially methylated histone H3, a pattern is emerging which separates between mammalian and nonmammalian orthologs. H. sapiens, P. troglodytes and M. musculus UHRF1 orthologs utilize the functionality of both TTD and PHD domains to interact with histone H3 peptides, while G. gallus, X. laevis, and D. rerio employ either TTD or PHD. Further, UHRF1 allosteric regulation by 16:0 PI5P is a unique case to primate orthologs where H3K9me3 peptide binding is enhanced upon hUHRF1 and pUHRF1 interacting with 16:0 PI5P. This is due to their closed and autoinhibited conformation wherein TTD is blocked by the PBR region in linker 4. 16:0 PI5P outcompetes TTD for PBR binding resulting in a release of TTD blockage, hence, enhanced H3K9me3 binding. However, owing to the lack of phosphatidylinositol binding specificity and reduced sequence conservation of linker 4, the regulatory impact of 16:0 PI5P in avian and lower vertebrate orthologs could not be detected. Additionally, all UHRF1 orthologs exert their ubiquitylation enzymatic activity on histone H3 substrates, supporting the notion that the overall functionality of UHRF1 orthologs is conserved, despite their divergent molecular approaches. Taken together, my findings suggest that UHRF1 orthologs adopt distinct conformational states with a differential response to the allosteric regulators 16:0 PI5P and hemi-methylated DNA. -
Arabidopsis SUMO protease ASP1 positively regulates flowering time partially through regulating FLC stability(Journal of Integrative Plant Biology, Wiley, 2017-01-10) [Article]The initiation of flowering is tightly regulated by the endogenous and environment signals, which is crucial for the reproductive success of flowering plants. It is well known that autonomous and vernalization pathways repress transcription of FLOWERING LOCUS C (FLC), a focal floral repressor, but how its protein stability is regulated remains largely unknown. Here, we found that mutations in a novel Arabidopsis SUMO protease 1 (ASP1) resulted in a strong late-flowering phenotype under long-days, but to a lesser extent under short-days. ASP1 localizes in the nucleus and exhibited a SUMO protease activity in vitro and in vivo. The conserved Cys-577 in ASP1 is critical for its enzymatic activity, as well as its physiological function in the regulation of flowering time. Genetic and gene expression analyses demonstrated that ASP1 promotes transcription of positive regulators of flowering, such as FT, SOC1 and FD, and may function in both CO-dependent photoperiod pathway and FLC-dependent pathways. Although the transcription level of FLC was not affected in the loss-of-function asp1 mutant, the protein stability of FLC was increased in the asp1 mutant. Taken together, this study identified a novel bona fide SUMO protease, ASP1, which positively regulates transition to flowering at least partly by repressing FLC protein stability.
