Function of the mammalian olfactory system depends on specialized olfactory sensory neurons (OSNs) that each express only one allele ("monoallelic") of one odorant receptor (OR) gene ("monogenic"). The lysine-specific demethylase-1 (LSD1) protein removes activating H3K4 or silencing H3K9 methylation marks
