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. H3 methylated...

Regulatory T cells play a crucial role in orchestrating immune response and maintaining immune tolerance, and the expression of the Foxp3 gene is indispensable to the differentiation of regulatory T cells. IL-4 shows strong inhibitory effects on Foxp3 expression and...

Glucocorticoid-induced TNFR-related protein (GITR) is a costimulatory molecule with diverse effects on effector T cells and regulatory T cells (Tregs), but the underlying mechanism remains poorly defined. Here we demonstrate that GITR ligation subverts the induction of Foxp3(+) Tregs and...

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...

Heterochromatin protein 1 (HP1) is localized at heterochromatin sites where it mediates gene silencing. The chromo domain of HP1 is necessary for both targeting and transcriptional repression. In the fission yeast Schizosaccharomyces pombe, the correct localization of Swi6 (the HP1...
