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 a nucleosome, the basic subunit of chromatin. Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. These modifications can alter local chromatin architecture, or recruit trans-acting factors that recognize specific histone modifications (the "histone code" hypothesis). The modifications occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Methylation of histone H3 on Lys36 (H3K36me2/3) is tightly associated with actively transcribed genes, and this modification is found primarily within the coding region, suggesting H3K36 methylation is necessary for efficient RNA polymerase II elongation and processivity.
