Preferential occupancy of histone variant H2AZ at inactive promoters influences local histone modifications and chromatin remodeling.
The yeast histone variant H2AZ (Htz1) is implicated in transcription activation, prevention of the ectopic spread of heterochromatin, and genome integrity. Our genome-wide localization analysis revealed that Htz1 is widely, but nonrandomly, distributed throughout the genome in an SWR1-dependent manner. We found that Htz1 is enriched in intergenic regions compared with coding regions. Its occupa...
متن کاملMapping post-translational modifications of the histone variant MacroH2A1 using tandem mass spectrometry.
Post-translational histone modifications modulate chromatin-templated processes and therefore affect cellular proliferation, growth, and development. Although post-translational modifications on the core histones have been under intense investigation for several years, the modifications on variant histones are poorly understood. We used tandem mass spectrometry to identify covalent modification...
متن کاملPost-translational modifications of tubulin
Microtubules are the largest filamentous components of the eukaryotic cytoskeleton. In spite of their extraordinary level of structural conservation, microtubules fulfill a vast range of different functions in cells. How this functional diversity is achieved remains an open question; however, recent advances point towards post-translational modifications (PTMs) of tubulin as a potent mechanism ...
متن کاملDynamics and dispensability of variant-specific histone H1 Lys-26/Ser-27 and Thr-165 post-translational modifications.
In mammals, the linker histone H1, involved in DNA packaging into chromatin, is represented by a family of variants. H1 tails undergo post-translational modifications (PTMs) that can be detected by mass spectrometry. We developed antibodies to analyze several of these as yet unexplored PTMs including the combination of H1.4 K26 acetylation or trimethylation and S27 phosphorylation. H1.2-T165 ph...
متن کاملLysine post-translational modifications and the cytoskeleton.
PTMs (post-translational modifications) of lysine residues have proven to be major regulators of gene expression, protein-protein interactions, and protein processing and degradation. This is of particular importance in regulating the cytoskeleton, an enormously complex system of proteins responsible for cell motility, intracellular trafficking, and maintenance of cell form and structure. The c...
