2017 Histone H3K9 methylation antibodies and relating products
1. Introuduction of H3K9me1, H3K9me2 and H3K9me3
H3K9 methylation is the mark of heterochromatin. Heterochromatin is the condensed, transcriptionally inactive state of chromatin. It can be facultative or constitutive. Mono, di, and tri H3K9 methylations each have very distinct distributions. H3K9me1 is enriched at the transcriptional start site of active genes (Barski et al., 2007). The same study found that H3K9me2 and 3 were both found more often at silenced genes. However it is important to note that for all these methylations that the correlations were modest, with many highly active genes showing strong H3K9me2/3 enrichment at their promoters. In mammals, these covalent modifications are catalyzed by five members of the SET-domain containing family of methyltransferases. SETDB1 and the related enzymes SUV39H1 and SUV39H2 contribute to both H3K9me2 and H3K9me3, while GLP and G9a (also called EHMT1 and EHMT2, respectively) catalyze H3K9me1 and H3K9me2. H3K9me2 and me3 are bound by the chromo-domain of Heterochromatin protein 1 (HP1, three isoforms in mammals), which can self-oligomerize and recruit repressive histone modifiers, contributing to heterochromatin compaction and spread. The methyltransferases that deposit H3K9me2 and H3K9me3 are required to establish high levels of DNA methylation at CpG dinucleotides and low levels of histone acetylation, two other hallmarks of heterochromatin. Kallestad et al. (2014) showed that H3K9me2/me3 was observed when transcription was inhibited during active replication. This process did not require the presence of H3K9me1, which appears to have a highly specific function and is a less commonly explored feature of the epigenome. Relatedly, Pinheiro et al. (2012) identified very important characteristics of H3K9me1. These authors revealed that the lysine-specific HMTs Prdm3 and Prdm16 are responsible for direct H3K9 mono-methylation in the cytoplasm. Then, in the nucleus, H3K9me1 is converted to H3K9me3 by the Suv39h1 enzyme, promoting hetero-chromatinization.

|Suv39H1||Suv39H1 antibody||Sulforaphane stimulates ubiquitination and acetylation of SUV39H1 within a C-terminal nuclear localization signal peptide motif and coincides with its dissociation from chromatin and a decrease in global H3K9me3 levels. Exogenous SUV39H1 expression leads to an increase in H3K9me3 and decreases sulforaphane-induced apoptotic signaling. SUV39H1 is thus identified as a novel mediator of sulforaphane cytotoxicity in PC3 cells.||Watson, GW; Wickramasekara, S; Palomera-Sanchez, Z; Black, C; Maier, CS; Williams, DE; Dashwood, RH; Ho, E.

|CBX1-8||CBX2 antibody||The eight mammalian Cbx proteins are chromodomain-containing proteins involved in regulation of heterochromatin, gene expression, and developmental programs. They are evolutionarily related to the Drosophila HP1 (dHP1) and Pc (dPc) proteins that are key components of chromatin-associated complexes capable of recognizing repressive marks such as trim-ethylated Lys-9 and Lys-27, respectively, on histone H3. However, the binding specificity and function of the human homologs, Cbx1–8, remain unclear. To this end we employed structural, biophysical, and mutagenic approaches to characterize the molecular determinants of sequence contextual methyl-lysine binding to human Cbx1–8 proteins. Although all three human HP1 homologs (Cbx1, -3, -5) replicate the structural and binding features of their dHP counterparts, the five Pc homologs (Cbx2, -4, -6, -7, -8) bind with lower affinity to H3K9me3 or H3K27me3 peptides and are unable to distinguish between these two marks. Additionally, peptide permutation arrays revealed a greater sequence tolerance within the Pc family and suggest alternative non-histone sequences as potential binding targets for this class of chromo domains.||Liu, Xing-Yong; Zhang, Xian-Bo; Li, Ming-Hui; Zheng, Shu-Qing; Liu, Zhi-Long; Cheng, Yun-Ying; Wang, De-Shou.
