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 ...

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.

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 ...

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 ...

Histones: annotating chromatin.
Annual Review of Genetics, 2009Chromatin is a highly regulated nucleoprotein complex through which genetic material is structured and maneuvered to elicit cellular processes, including transcription, cell division, differentiation, and DNA repair.

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.

Histones and Their Modification
Critical Reviews in Biochemistry, 1986Histones constitute the protein core around which DNA is coiled to form the basic structural unit of the chromosome known as the nucleosome. Because of the large amount of new histone needed during chromosome replication, the synthesis of histone and DNA is regulated in a complex manner.
