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. While lysine demethylation is mediated by enzymes such as JmjC domain-containing proteins.


This antibody recognizes Histone H3 unmethylated at Lys9. This antibody does not cross react with methyl-Histone (Lys29). This antibody detects unmethylated Histone H3 (Lys9) when Ser10 is phosphorylated.


KLH-conjugated linear peptide corresponding to human unmethylated Histone H3 (Lys9).
