Lysine-specific demethylase 1 (LSD1) is a human protein encoded by the kdm1a gene. Specifically, LSD1 is a flavin-dependent monoamine oxidase that demethylates monomethyl and dimethyllysine, especially H3K4 and H3K9. Besides, LSD1 regulates a variety of biological processes through dual function regulation of enhancer function. Overexpression of LSD1 is a...
