malfunction | depletion of LSD1 in an immortalized olfactory-placode-derived cell line (OP6) results in multigenic and multiallelic odorant receptor (OR) transcription per cell, while not seemingly disrupting the ability of these cells to activate new OR genes during clonal expansion. LSD1 depletion does not seem to alter OR representation in OP6 cell populations. Apparent systematic accumulation of H3K4me2 (and possibly H3K9me2) in LSD1-depleted cell populations | Mus musculus |
physiological function | function of the mammalian olfactory system depends on specialized olfactory sensory neurons (OSNs) that each express only one allele of one odorant receptor (OR) gene (monogenic). The lysine-specific demethylase-1 (LSD1) has a role in silencing additional OR alleles in the immortalized olfactory-placode-derived cell line (OP6) cellular context. LSD1 protein removes activating H3K4 or silencing H3K9 methylation marks in a variety of developmental contexts | Mus musculus |
