Abstract

Three years after its discovery, lysine-specific demethylase 1 remains at the forefront of chromatin research. Its demethylase activity on Lys4 of histone H3 supports its role in gene repression. By contrast, the biochemical mechanisms underlying lysine-specific demethylase 1 involvement in transcriptional activation are not firmly established. Structural studies highlight a specific binding site for the histone H3 N-terminal tail and a catalytic machinery that is closely related to that of other flavin-dependent amine oxidases. These insights are crucial for the development of demethylation inhibitors. Furthermore, the exploration of putative nonhistone substrates and potential signaling roles of hydrogen peroxide produced by the demethylation reaction could lead to new paradigms in chromatin biology.
