WebOct 15, 2000 · Dephosphorylation of H1 and H3 are not likely to be the only damage-induced posttranslational modifications of histones. It is likely that multiple modifications (phosphorylation, acetylation, methylation, and ubiquitination) as proposed by Strahl (55) acting in a combinatorial or sequential fashion specify unique downstream functions. While most histone H1 in the nucleus is bound to chromatin, H1 molecules shuttle between chromatin regions at a fairly high rate. It is difficult to understand how such a dynamic protein could be a structural component of chromatin, but it has been suggested that the steady-state equilibrium within the nucleus still strongly favors association between H1 and chromatin, meaning that despite its dynamics, the v…
