The discovery of histone demethylases.
Histone methylation is a key element of the eukaryotic epigenome. Since the discovery of the first histone demethylase (HDM) in 2004, more than 20 demethylases have been identified and characterized. They belong to either the LSD family or the JmjC family, demonstrating the reversibility of all methylation states at almost all major histone lysine methylation sites. These findings ended decades...
متن کاملInterfering with histone demethylases in HSCs.
S tem cells are governed by epigenetic mechanisms that can either help maintain the necessary gene expression programs to preserve the stem cell state or ensure the establishment of new cell-specific expression programs during differentiation. One important level of epigenetic control originates from histone modifications such as methylation or acetylation. These modifications can be associated...
متن کاملDevelopmental roles of the histone lysine demethylases.
Since the discovery of the first histone lysine demethylase in 2004, two protein families with numerous members have been identified that demethylate various histone lysine residues. Initial studies of the histone lysine demethylases focused on their in vitro enzymatic activity but, more recently, model organisms have been used to examine the roles of these enzymes in vivo. Here, we review rece...
متن کاملHistone demethylases in chromatin biology and beyond
Histone methylation plays fundamental roles in regulating chromatin-based processes. With the discovery of histone demethylases over a decade ago, it is now clear that histone methylation is dynamically regulated to shape the epigenome and regulate important nuclear processes including transcription, cell cycle control and DNA repair. In addition, recent observations suggest that these enzymes ...
متن کاملHistone lysine demethylases in Drosophila melanogaster
Epigenetic regulation of chromatin structure is a fundamental process for eukaryotes. Regulators include DNA methylation, microRNAs and chromatin modifications. Within the chromatin modifiers, one class of enzymes that can functionally bind and modify chromatin, through the removal of methyl marks, is the histone lysine demethylases. Here, we summarize the current findings of the 13 known histo...
