This is a Histone 3 lysine 36 dimethylated peptide. This peptide has been shown to recruit histone deacetylase complex with nucleosomes and repress transcription. In addition, owing to its epigenetic repressive mark, it allows demethylation by a Jumonji C-domain family member, JMJD5 that functions as a transcription activator by inhibiting HDAC, and regulates cell cycle proliferation.
This peptide is Histone H3 amino acid residues 21 to 44 di-methylated at Lys-36 with an additional C-terminal glycine followed by a biotinylated lysine. Provided at >95% peptide purity, this peptide was dissolved in distilled water at 1 mg/ml and re-lyophilized to powder form
