Human recombinant LSD1 expressed in E. Coli
LSD1 catalyzes the oxidative demethylation of mono- and dimethylated H3K4, producing hydrogen peroxide and formaldehyde in the process. H3K4 methylation is considered a transcription-activating chromatin mark, and in vivo LSD1 is frequently found in association with the transcriptional corepressor protein CoREST and HDACs 1 or 2. LSD1 is inhibited by a number of established monoamine oxidase inhibitor drugs. That and the fact that its expression is elevated in a number of cancers may make it a promising target for drug development.
