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. … WebWhen the (histone) tail affects the brain. Nat Struct Mol Biol. 2024 Apr 12. doi: 10.1038/s41594-023-00979-9.
