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. … WebThe The H1 CTD also has been shown to mediate the protein-protein interac- broader implication is that the linker histone CTD actually is a specific type of tions involved in H1-dependent activation of the apoptotic nuclease, DFF40/ IDP region that is found in different locations within different proteins.
