Yeast inner histones and the evolutionary conservation of histone-histone interactions
Biochemistry, 1978The inner histones of the yeast, Saccharomyces cerevisiae, have been isolated and identified by their amino acid compositions. H4 appears to be close to its calf and pea counterparts. H2a, H2b, and H3 have diverged. The isolation of the histones was accomplished by consecutive slab-gel fractionation, and a number of novel features of the method are ...

Histone Variants and Histone Modifications in Neurogenesis
Trends in Cell Biology, 2020During embryonic brain development, neurogenesis requires the orchestration of gene expression to regulate neural stem cell (NSC) fate specification. Epigenetic regulation with specific emphasis on the modes of histone variants and histone post-translational modifications are involved in interactive gene regulation of central nervous system (CNS ...

Archaeal histones and the origin of the histone fold
Current Opinion in Microbiology, 2006Histone sequences have been identified in many archaeal genomes and in environmental samples, and they constitute a family of proteins that are structural homologs of the eukaryotic core histones. Most archaeal histones conform to the single histone-fold structural models that have been described, but a few histone variants exhibit short insertions ...

SummaryThe histones are responsible for packaging and regulating access to eukaryotic genomes. Trypanosomatids are flagellated protists that diverged early from the eukaryotic lineage and include parasites that cause disease in humans and other mammals.

Analysis of Histones and Histone Variants in Plants [PDF]
, 2011 Histone proteins are the major protein components of chromatin - the physiologically relevant form of the genome (or epigenome) in all eukaryotic cells. For many years, histones were considered passive structural components of eukaryotic chromatin. In recent years, it has been demonstrated that dynamic association of histones and their variants to the ...

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970
Abstract An investigation was made into the nature and extent of phosphorus and of nonhistone phosphorylated molecular species in histones and histone fractions. The distributions of radiophosphorus, of labeled nucleic acid precursors and of intact labeled nucleic acids during histone preparation and fractionation were presented.

Methods, 2003
Dynamic histone acetylation has a role in chromatin remodeling and in the regulation of transcription. Histone deacetylases (HDACs) and histone acetyltransferases (HATs) catalyze reversible histone acetylation. HATs and HDACs exist as multiprotein complexes that have coactivator and corepressor activities, respectively.

Influence of histone phosphorylation upon histone-histone interactions studied in vitro
Biochemistry, 1980Histones H2b and H3, phosphorylated in vitro with the catalytic subunit of protein kinase I from rabbit skeletal muscle, were used to estimate the influence of histone phosphorylation upon histone-histone complex formation. Stoichiometry and interaction affinity of the complexes H2a-H2b, H4-H2b, and H4-H3 were determined by using the continuous ...

The evolution of histones [PDF]
Journal of Molecular Evolution, 1978 The amino acid sequences of bovine histones H2A, H2B, H3, and H4 and the first 107 residues of rabbit thymus histone H1 were examined using newly developed procedures designed to detect and evaluate weak similarities (de Haën et al., 1976). Using the McLachlan scoring system, regions of statistically significant similarity were found between several ...
