Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming the nucleosome. Histones are modified post-translationally; and these modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. Phosphorylation at Ser10, which is linked to gene activation, prevents methylation at Lys9 but facilitates acetylation of H3 and H4. Phosphorylated Ser10 is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. In addition, Ser10 phosphorylation is also an essential regulatory mechanism for neoplastic cell transformation. Phosphorylation at Ser10 by Aurora-B mediates the dissociation of HP1 proteins (CBX1, CBX3 and CBX5) from heterochromatin.
