Summary

It is proposed that the singular phosphorylation of the amino-terminus of histone H3 may be involved in facilitating two key functions during mitosis: (1) regulate protein-protein interactions to promote binding of trans-acting factors that “drive” chromatin condensation as cells enter M-phase and (2) coordinate chromatin decondensation associated with M- phase.
