It has been proposed that this phosphorylation of H1, by cyclin-dependent kinases (CDKs), controls the level of chromatin condensation as cells traverse the cell cycle ( Roth and Allis, 1992 ).
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…
