Histone Modification Antibodies

Histone modification antibodies are used to investigate epigenetic modifications to histones such as acetylation, methylation, and phosphorylation. Histone methylation is associated with transcriptional repression or activation via the transfer of methyl groups to lysine or arginine residues of histone proteins and is crucial to studying epigenetic gene regulation with the use of histone methylation antibodies. Histone methyltransferases (HMTs) are responsible for catalyzing this process. Similarly, histone acetylation antibodies can be used to study chromatin remodeling and epigenetic gene regulation that occurs as a result of histone acetylation. This histone modification is defined as the addition of an acetyl group to lysine residues of histone proteins by enzymes known as histone acetyltransferases (HATs), and is associated with gene activation and expression.
