Simple Detection of JumonjiC Histone Demethylase and Dioxygenase Activity
JumonjiC domain-containing histone lysine demethylases (JMJCs) play a pivotal role in determining the epigenetic status of the genome by counteracting the activities of histone lysine methyltransferases. These enzymes act as erasers by catalyzing the removal of methyl marks from specific lysine sites in histones, leading to either transcriptional repression or activation of target genes.
The Succinate-Glo™ JmjC Demethylase/Hydroxylase Assay rapidly detects succinate formation in JumonjiC histone demethylase and Fe(II)/α-ketoglutarate-dependent dioxygenase reactions. The assay uses the reaction product, succinate, to form ATP, which drives a bioluminescent reaction to produce a signal proportional to the original demethylase/hydroxylase activity.
