Abstract
The recent discovery that histone demethylation can be catalyzed by the flavin-dependent amine oxidase LSD1 has ushered in a new chapter in the chromatin-remodeling community. Herein, we discuss the rapid progress of the histone demethylase field including the recent identification of the non-heme iron-dependent histone demethylases (JmjC family), the basis for LSD1 substrate site specificity and the newly emerging potential for inhibition of these enzymes in structural and functional analysis.
