Crystal structure of human histone lysine-specific demethylase 1 (LSD1).
Lysine-specific demethylase 1 (LSD1) was recently identified as the first histone demethylase that specifically demethylates monomethylated and dimethylated histone H3 at K4. It is a component of the CoREST and other corepressor complexes and plays an important role in silencing neuronal-specific genes in nonneuronal cells, but the molecular mechanisms of its action remain unclear. The 2.8-A-re...
متن کاملVisualizing the Histone Code on LSD1
In this issue, Garcia-Bassets et al. (2007) show that spurious transcriptional activation by unliganded nuclear receptors is inhibited by histone lysine methylation. This inhibitory histone modification code is efficiently countered by the ligand-dependent recruitment of histone lysine demethylases, including lysine-specific demethylase 1 (LSD1), which appear to be used for this purpose by a nu...
متن کاملThe histone demethylase LSD1/KDM1A promotes the DNA damage response
Histone demethylation is known to regulate transcription, but its role in other processes is largely unknown. We report a role for the histone demethylase LSD1/KDM1A in the DNA damage response (DDR). We show that LSD1 is recruited directly to sites of DNA damage. H3K4 dimethylation, a major substrate for LSD1, is reduced at sites of DNA damage in an LSD1-dependent manner. The E3 ubiquitin ligas...
متن کاملHistone demethylase LSD1 controls the phenotypic plasticity of cancer cells
Epigenetic mechanisms underlie the phenotypic plasticity of cells, while aberrant epigenetic regulation through genetic mutations and/or misregulated expression of epigenetic factors leads to aberrant cell fate determination, which provides a foundation for oncogenic transformation. Lysine-specific demethylase-1 (LSD1, KDM1A) removes methyl groups from methylated proteins, including histone H3,...
متن کاملThe histone LSD1 demethylase in stemness and cancer transcription programs.
DNA and histone chromatin modifying enzymes play a crucial role in chromatin remodeling in several biological processes. Lysine-specific demethylase 1 (LSD1), the first identified histone demethylase, is a relevant player in the regulation of a broad spectrum of biological processes including development, cellular differentiation, embryonic pluripotency and cancer. Here, we review recent insigh...
