General description

Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the ′beads on a string′ structure. Histone proteins are highly post-translationally modified however Histone H3 is the most extensively modified of the five histones. Histone H3 sequence variants and variable modification states are thought to play a role in the dynamic and long term regulation of genes. Trimethylation of histone H3 on Lys9 (H3K9me3) is one of the most highly studied epigenetic marks. H3K9me3 functions in the repression of euchromatic genes, and in epigenetic control of heterochromatin assembly, most likely by acting as a recognition motif for the binding of chromatin-associated proteins, such as Swi6 or HP1α. The enzymes responsible for H3K9 trimethylation are SUV39H1 and SUV39H2.

Specificity

Broad species cross-reactivity is expected, based on sequence homology.
This antibody recognizes Histone H3 trimethylated at Lys9. Some cross-reactivity with dimethyl Lys9 is detected at higher concentrations, but the difference in specificity is >27-fold1. Phosphorylation of Ser10 interferes with antibody binding to trimethyl Lys91.

Immunogen

Epitope: Trimethyl Lys9
Synthetic peptide corresponding to amino acids 1-19 of human Histone H3, trimethylated on Lys9, conjugated to KLH.

Mouse and cell-based studies have shown that macroH2A histone variants predominantly associate with heterochromatin. Functional studies found that macroH2As are involved in gene repression, inhibiting the acquisition of pluripotency and preserving cell differentiation. However, only a few studies have analysed

Histone H3 lysine 9 trimethylation (H3K9Me3) has been associated with transcriptional repression, but recent findings implicate this chromatin modification in transcriptional activation and mRNA elongation by RNA polymerase II. Here, we applied immunoprecipitation (IP) with a custom DNA tiling microarray
