Analysis of Histones and Histone Variants in Plants
2011Histone 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 ...

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.

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.

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 ...

Linker histones of which histone H1 is a representative are a diverse family of architectural proteins within the eukaryotic nucleus. These proteins have a variety of structures, but invariably contain a region enriched in lysine, serine, alanine and proline.

Post-translational modification of the histones of chromatin has a fundamental role in regulating gene expression. Enzymes involved in these epigenetic events include histone deacetylases (class I and class II), which can be inhibited by a structurally diverse group of small molecules.

Abstract The meiotic cells in the anthers of lily and tulip contain a unique histone which is absent or nearly so, from the somatic tissues of these plants. This histone, termed the meiotic histone, is synthesized during the premeiotic histone synthesis, persists through meiosis, microsporogenesis, and pollen maturation.

Abstract The biological roles of the histones are multiple; by complexing to DNA they cause such DNA to be inactive as a template for RNA polymerase; they cause supercoiling of the DNA which would appear to be a fundamental requirement for further orders of supercoiling, presumable exemplified by metaphase chromosomes; a particular histone even forms

Abstract A study of the effect of dialysis on histone preparations obtained from calf thymus nucleoprotein by different methods showed that amount and characteristics of dialyzable material vary with the mode of preparation and the pH of the dialyzing medium. A modified assembly for fractional dialysis is described.

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.
