Brief introduction to post-translational modifications

As described above, histones are much more than passive structural players within chromatin. Dynamic post-translational modifications of these proteins confer specialized chemical proprieties to chromatin of both informational and structural nature with important functional implications. The highly conserved sites for acetylation, methylation, phosphorylation, ADP-ribosylation, and ubiquitination events on histone tails appear to orchestrate functional activities that range from transcriptional activation and repression to DNA repair and recombination. [Pg.249]
