A portion of amino acids 108-142 from the human protein was used as the immunogen for this LSD1 antibody.
LSD1 is a histone demethylase that specifically demethylates Lys-4 of histone H3, a specific tag for epigenetic transcriptional activation, thereby acting as a corepressor. LSD1 contains a SWIRM domain, a FAD-binding motif, and an amine oxidase domain. This protein is a component of several histone deacetylase complexes, though it silences genes by functioning as a histone demethylase. It acts by oxidizing the substrate by FAD to generate the corresponding imine that is subsequently hydrolyzed. LSD1 demethylates both mono- and tri-methylted Lys-4 of histone H3. This protein may play a role in the repression of neuronal genes. Alone, it is unable to demethylate H3 Lys-4 on nucleosomes and requires the presence of RCOR1/CoREST to achieve such activity. It may also demethylate Lys-9 of histone H3, a specific tag for epigenetic transcriptional repression, thereby leading to derepression of androgen receptor target genes.
