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.
