Histone - Wikipedia, the free encyclopedia

In biology, histones are the chief protein components of chromatin. They act as spools around which DNA winds, and they play a role in gene regulation. Without histones, the unwound DNA in chromosom...

Non-histone protein - Wikipedia, the free encyclopedia
In chromatin, those proteins which remain after the histones have been removed, are classified as non-histone proteins . Scaffold proteins, DNA polymerase, Heterochromatin Protein 1 and Polycomb are...

Histones are the major structural proteins of chromosomes. The DNA molecule is wrapped twice around a Histone Octamer to make a Nucleosome. Six Nucleosomes are assembled into a Solenoid in association with H1 histones.

Histone proteins are essential for the packaging of DNA into chromosomes within the nucleus of a cell. They also control, in some degree, the expression of proteins from DNA. Histone proteins play an important role in DNA packaging, chromosome stabilization and gene expression.

The synthesis of histone proteins in G1 and S phase HeLa S3 cells was examined by two-dimensional electrophoretic fractionation of nuclear and total cellular proteins. Newly synthesized histones were detected only in S phase cells.

In this study, we have screened over 30 histone variants, modified histones and non-histone proteins for their association with or exclusion from the Barr body.

We show that the human homologues of two novel putative histone-fold proteins in Drosophila CHRAC are present in HuCHRAC. The two human histone-fold proteins form a stable complex that binds naked DNA but not nucleosomes.

CAF-1, Hir proteins, and Asf1 are histone H3/H4 binding proteins important for chromatin-mediated transcriptional silencing. We explored genetic and physical interactions between these proteins and S-phase/DNA damage checkpoint kinases in the budding yeast Saccharomyces cerevisiae.
