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 ...

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 ...

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.

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.

AbstractHistones occur in equal amounts to DNA in the cell nucleus and are largely responsible for the compaction of the genome into chromatin via the formation of nucleosomes and higher‐order structures. Whereas two of the five histone types exhibit little structural variation, the remaining three occur in many variant tissue‐ or species‐specific ...

Histone variants and histone modifications: A structural perspective
Biochemistry and Cell Biology, 2001In this review, we briefly analyze the current state of knowledge on histone variants and their posttranslational modifications. We place special emphasis on the description of the structural component(s) defining and determining their functional role. The information available indicates that this histone "variability" may operate at different levels:
