背景

Protein Background: Recombinant nucleosomes are widely used in histone methyltransferase screening assays to identify small molecular inhibitors for drug discovery. Histone H3.1 and Histone H3.3 are the two main Histone H3 variants found in plants and animals and are known to be important for gene regulation. Histone H3.1 and H3.3 demonstrate unique genomic localization patterns thought to be associated with their specific functions in regulation of gene activity. Specifically, Histone H3.3 primarily co-localizes with marks associated with gene activation (H3K4me3, H2BK120ub1, and RNA pol II occupancy). Deposition of the Histone H3.1 variant into the nucleosome correlates with the canonical DNA synthesis-dependent deposition pathway, whereas Histone H3.3 primarily serves as the replacement Histone H3 variant outside of S-phase, such as during gene transcription. Histones are linked to tumorigenesis primarily through alterations in their PTMs and the enzymes regulating these modifications, suggesting that they might disrupt the reading, writing, and/or erasing of these marks. Except for being near K9, which can be methylated or acetylated, R8 site itself can be methylated too. Mutations in histone H3 occur with high genetic penetrance within rare gliomas and sarcomas. Researchers have found that histones containing mutations at H3 N-terminal residues at or near PTM sites including R2, R8, K18 and R26 may be considered as oncogenic.
Short Description: Recombinant Mononucleosomes H3.3 (K9I) consist of a 167 bp of 601 DNA and two molecules each of histones H2A that includes amino acids 1-130 (end) (accession number NM_003512), H2B that includes amino acids 1-126 (end) (accession number NM_003518), H3.3 that includes amino acids 1-136 (end) (accession number NM_005324) with a point mutation Lys9Ile, and H4 that includes amino acids 1-103 (end) (accession number NM_003548). All of these histones were expressed in E. coli cells. The molecular weight of histone octamer is 108 kDa.
