Kinetics of histone gene expression during early development of Xenopus laevis.

Abstract:
Using literature data for transcriptional and translational rate constants, gene copy numbers, DNA concentrations, and stability constants, we have calculated the expected concentrations of histones and histone mRNA during embryogenesis of Xenopus laevis. The results led us to conclude that: (i) for X. laevis the gene copy number of the histone genes is too low to ensure the synthesis of sufficient histones during very early development, inheritance from the oocyte of either histone protein or histone mRNA (but not necessarily both) is necessary; (ii) from the known storage of histones in the oocyte and the rates of histone synthesis determined by Adamson and Woodland (1977), there would be sufficient histones to structure the newly synthesized DNA up to gastrulation but not thereafter (these empirical rates of histone synthesis may be underestimates); (iii) on the other hand, the amount of H3 mRNA recently observed during early embryogenesis (Koster, 1987, Koster et al., 1988) could direct a higher and sufficient synthesis of H3 protein, also after gastrulation. We present a quantitative model that accounts both for the observed H3 mRNA concentration as a function of time during embryogenesis and for the synthesis of sufficient histones to structure the DNA throughout early embryogenesis. The model suggests that X. laevis exhibits a major (i.e. some 14-fold) reduction in transcription of histone genes approximately 11 hours after fertilization. This reduction could be due to a decrease in the number of transcribed histone genes, a decreased rate constant of transcription with continued transcription of all the histone genes, and/or a reduction in the time during the cell cycle in which histone mRNA synthesis takes place. Alternatively, the histone mRNA stability might decrease approximately 16-fold 11 hours after fertilization.

Project description:We identify the Kcr sites on histones that are targeted by CDYL in ADPKD cells (WT9-12 cells). We chose to knock out CDYL in WT 9-12 cells (CDYL KO) through CRISPR/Cas9-mediated gene editing to increase the overall levels of histone Kcr. We quantified Kcr modifications on different histone residues in CDYL KO versus parental WT 9-12 cells (control) using high-resolution liquid chromatography tandem mass spectrometry (LC-MS/MS)-based proteomics analysis

Project description:We performed RNA-seq across the yeast metabolic cycle (YMC) in wild-type and a strain lacking ARP5, a central component of the INO80 chromatin remodelling complex. We also perform ATAC-seq on the same samples to examine chromatin architecture across the YMC.

Project description: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 H3 and recombinant wild type histone H4 (unmod. H3), 2. recombinant wild type histone H3 and ligated unmodified histone H4 (unmod. H4) 3. ligated unmodified histones H3 and H4 (unmod. H3&H4). 4. recombinant wild type histones H3 and H4 (WT) Each pull-down was performed in three replicates. Co-purified proteins were quantified using label-free MS. Note that ligated histones H3 and H4 contain T32C or I29C single amino acid substitutions, respectively, that are introduced by the native chemical ligation procedure. In addition, ligated histone H4 is N-terminally acetylated to mimic its naturally blocked N-terminus.

Project description:Lysine crotonylation on histones is a recently identified post-translational modification that has been demonstrated to associate with active promoters and to directly stimulate transcription.Given that crotonyl-CoA is essential for the acyl transfer reaction and it is a metabolic intermediate widely localized within the cell, we postulate that lysine crotonylation on non-histone proteins could also widely exist. Using specific antibody to enrich crotonylated lysine(Kcr) peptides followed by high-resolution mass spectrometry analysis reveals that crotonylated proteins and lysine residues. Bioinformatic analysis reveals that crotonylated proteins are particularly enriched in the nuclei, that lysine crotonylation alters level of the modified proteins in the chromatin and that cotonylation of a subset of proteins influences DNA replication and cell cycle. Taken together, our data indicate that lysine crotonylation could be induced in a large number of proteins other than histones and this type of acyl modification could play an important role regulating multiple cellular processes.
