The methylation of lysine residues on histones plays a central role in determining euchromatin structure and gene expression. The histone methyltransferase (HMTase) G9a can mono- or dimethylate lysine 9 on histone 3 (H3), contributing to early embryogenesis, genomic imprinting, and lymphocyte development. BIX01294 (hydrochloride hydrate) is a selective inhibitor of G9a HMTase (IC50 = 1.7 μM). It less effectively inhibits the HMTase G9a-like protein (GLP; IC50 = 38 μM) and has no effect on other known HMTases. BIX01294 has been used in combination with the calcium channel activator BayK8644 to facilitate the generation of induced pluripotent stem cells from somatic cells in vitro.

Histone H3 (21-44)-GK-biotin is a peptide fragment of histone H3 that corresponds to amino acid residues 22-45 of the human histone H3.1 and 3.2 sequences and is biotinylated via a C-terminal GK linker. Histone H3 (21-44) contains a lysine residue at position 23 that is subject to acetylation, an arginine at position 26 subject to methylation, and a serine at position 28 subject to phosphorylation, as well as lysine residues at positions 27 and 36 that are subject to methylation and acetylation. Histone H3 (21-44)-GK-biotin has been used as a substrate for the primate-specific histone methyltransferase PR domain-containing protein 7 (PRDM7) to determine substrate specificity.

Lysine-specific demethylase inhibitor (1C) (LSD inhibitor (1C)) is an inhibitor of LSD1, a repressive demethylase selective for histone H3 lysine 4 (H3K4).1,2LSD inhibitor (1C) inhibits LSD1 activity by 85.9% when used at a concentration of 10 μM.1It increases the level of H3K4 methylation, including H3K4me1 and H3K4me2 but not H3K9me2 levels, in HCT116 human colon carcinoma cells.2LSD inhibitor (1C) also induces re-expression of the Wnt signaling pathway proteins secreted frizzle-related protein 1 (SFRP1), SFRP4, and SFRP5, as well as the transcription factor GATA5, which are aberrantly silenced in HCT116 cells.

Histone H3 (21-44)-GK-biotin is a peptide fragment of histone H3 that corresponds to amino acid residues 22-45 of the human histone H3.3 sequence and is biotinylated via a C-terminal GK linker. Unlike histone H3.1 and H3.2, the histone H3.3 variant contains a serine residue at position 31 that is phosphorylated during late prometaphase and metaphase of mitosis. Histone H3 (21-44) also contains lysine residues at positions 23, 27, and 36 that are subject to methylation and acetylation, all of which have a role in the regulation of gene expression, and a serine residue at position 28 that is subject to phosphorylation during mitosis.

Histone H3 (21-44), derived from a sequence of 21-44 amino acids of histone H3, is commonly employed as a substrate, particularly for protein arginine methyltransferase assays, where methylation activity is being examined.

Histone H3 (23-34) is a peptide consisting of amino acid residues 23 to 34 of the histone H3 protein. This peptide specifically includes lysine residues at positions 23 and 27, which can undergo methylation and acetylation modifications.

TC-5115 is a potent inhibitor of MLL methyltransferase with IC50 value of 16 nM. TC-5115 may lead to the development of a new therapy for the treatment of human MLL leukemia. The mixed-lineage leukemia (MLL) protein, also known as MLL1, is a lysine methyltransferase specifically responsible for methylation of histone 3 lysine 4. MLL has been pursued as an attractive therapeutic target for the treatment of acute leukemia carrying the MLL fusion gene or MLL leukemia.

INCB059872, also known as INCB59872, is a potent, selective, and orally active lysine-specific demethylase 1 inhibitor. INCB059872 binds to and inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone H3 (H3K4) to mono- and unmethylated H3K4, respectively, through amine oxidation. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor-suppressor genes. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes.
