Background InformationHistone H3.3 (UniProt: P84243) is encoded by the H3F3A (also known as H3.3A, H3F3, PP781, H3F3B, H3.3B) gene (Gene ID: 3020) in human. It is a highly conserved variant form of Histone H3, which replaces conventional H3 in a wide range of nucleosomes in active genes. Histone H3.3 constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. H3.3 is associated with actively expressed genes in both animals and plants. It is predominantly enriched near transcription end sites (TES) of genes and positively associated with transcription. Histone H3 contains a main globular domain and a long N-terminal tail and is involved with the structure of the nucleosomes of the 'beads on a string' structure. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine. For example, acetylation on Lys10 (H3K9ac; initial methionine removed) impairs methylation at Arg9 (H3R8me2s) and acetylation on Lys19 (H3K18ac) and Lys24 (H3K24ac) favors methylation at Arg18 (H3R17me). Phosphorylation at Ser11 (H3S10ph) by Aurora kinase B is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis. Phosphorylation at Ser11 by RPS6KA4 and RPS6KA5 is important during interphase because it enables the transcription of genes following external stimulation, like mitogens, stress, growth factors or UV irradiation and result in the activation of genes, such as c-Fos and c-Jun. Mutations in Histone H3.3 have been implicated in a high proportion of malignant pediatric brain cancers. The mutant H3.3 histone disrupts epigenetic post-translational modifications near genes involved in cancer processes and in brain function. K36I mutations in Histone H3 have been reported in pediatric undifferentiated sarcoma tumors. K36I mutation is shown to inhibit H3K36 methylation, which can lead to a genome-wide gain in H3K27 methylation that leads to redistribution of polycomb repressive complex 1 and de-repression of its target genes to block mesenchymal differentiation.
