In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei. They act as spools around which DNA winds to create structural units called nucleosomes. Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. … WebAug 13, 2007 · In the past decade, knowledge about this modification has exploded, with targets rapidly expanding from histones to transcription factors and other nuclear proteins, and then to cytoskeleton,...
