General description

Histone methylation is a complex, dynamic process involved in a number of processes, including transcriptional regulation, chromatin condensation, mitosis and heterochromatin assembly. Conserved lysine residues in the N-terminal tail domains of histone H3, Lys4, Lys9 and Lys27 are the preferred sites of methylation. SET domain-, site-specific histone methyltransferases (HMTases) are involved in methylation of Lys9 in histone 3.

Specificity

ChIP validated

Immunogen

synthetic methylated peptide corresponding to amino acids 5-13 (diMe-Lys9) of human histone H3, conjugated to KLH. This sequence is identical in many species including mouse, rat, bovine, chicken, frog, Drosophila, C. elegans, tetrahymena, and Arabidopsis thaliana histone H3.

Application

Anti-dimethyl-Histone H3 (diMe-Lys9) antibody produced in rabbit has been used in immunoblotting and chromatin immunoprecipitation assay.

Biochem/physiol Actions

Mono- and dimethylation of H3 at Lys9 are intrinsically linked to epigenetic silencing and heterochromatin assembly. Methylation of H3 at Lys9 generates a binding site for HP1 proteins, a family of heterochromatic adaptor proteins implicated in both gene silencing and in the organization of higher order chromatin.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Eukaryotic genomes are organized into discrete structural and functional chromatin domains. Here, we show that distinct site-specific histone H3 methylation patterns define euchromatic and heterochromatic chromosomal domains within a 47-kilobase region of the mating-type locus in fission yeast.

Distinct modifications of histone amino termini, such as acetylation, phosphorylation and methylation, have been proposed to underlie a chromatin-based regulatory mechanism that modulates the accessibility of genetic information. In addition to histone modifications that facilitate gene activity, it is of

The assembly of higher order chromatin structures has been linked to the covalent modifications of histone tails. We provide in vivo evidence that lysine 9 of histone H3 (H3 Lys9) is preferentially methylated by the Clr4 protein at heterochromatin-associated regions
