        Histone Methyltransferase Activity/Inhibition Assay Kit (H3-K27)

        Cat.No. : Kit-0461
        Product Overview : Histone Methyltransferase Activity/Inhibition Assay Kit (H3-K27) is use for measuring HMT activity/inhibition.
        Description : Epigenetic inactivation of genes plays a critical role in many important human diseases, especially in cancer. A major mechanism for epigenetic inactivation of the genes is methylation of CpG islands in genome DNA caused by DNA methyltransferases. Histone methyltransferases (HMTs) control or regulate DNA methylation through chromatin-dependent transcription repression or activation. HMTs transfer 1-3 methyl groups from S-adenosyl-L-methionine to the lysine and arginine residues of histone proteins. Inhibition of HMTs may lead to expression of the silenced genes and HMT inhibitors are currently developed for various therapeutic or experimental applications. G9a and polycomb group enzyme such as EZH2 are histone methyltransferases that catalyze methylation of histone H3 at lysine 27 (H3-K27) in mammalian cells. H3-K27 methylation mediates heterochromatin formation by forming a binding site for polycomb and also participates in silencing gene expression at euchromatic sites. Increased H3- K27 methylation is also found to be involved in some pathological processes such as cancer progression. There is no method currently used for measuring HMT activity/ inhibition (H3-K27). The Histone Methyltransferase Activity/ Inhibition Assay Kit (H3-K27) addresses this problem by using a unique procedure to measure HMT activity/inhibition (H3-K27).
        Applications : For specifically measuring the activity/inhibition of individual histone methyltransferase targeting to lysine residues at different sites.
        Usage : For research use only (RUO)
        Storage : Upon receipt, store HE3, HE4, HE5, HE7, and control enzyme at –20°C away from light. Store all other components at 4°C away from light. The components of the kit should be stable for 6 months when stored properly.
