Function

KDM1A_HUMAN Histone demethylase that demethylates both 'Lys-4' (H3K4me) and 'Lys-9' (H3K9me) of histone H3, thereby acting as a coactivator or a corepressor, depending on the context. Acts by oxidizing the substrate by FAD to generate the corresponding imine that is subsequently hydrolyzed. Acts as a corepressor by mediating demethylation of H3K4me, a specific tag for epigenetic transcriptional activation. Demethylates both mono- (H3K4me1) and di-methylated (H3K4me2) H3K4me. May play a role in the repression of neuronal genes. Alone, it is unable to demethylate H3K4me on nucleosomes and requires the presence of RCOR1/CoREST to achieve such activity. Also acts as a coactivator of androgen receptor (ANDR)-dependent transcription, by being recruited to ANDR target genes and mediating demethylation of H3K9me, a specific tag for epigenetic transcriptional repression. The presence of PRKCB in ANDR-containing complexes, which mediates phosphorylation of 'Thr-6' of histone H3 (H3T6ph), a specific tag that prevents demethylation H3K4me, prevents H3K4me demethylase activity of KDM1A. Demethylates di-methylated 'Lys-370' of p53/TP53 which prevents interaction of p53/TP53 with TP53BP1 and represses p53/TP53-mediated transcriptional activation. Demethylates and stabilizes the DNA methylase DNMT1. Required for gastrulation during embryogenesis. Component of a RCOR/GFI/KDM1A/HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development.[1] [2] [3] [4] [5]

Publication Abstract from PubMed

Lysine-specific demethylase 1 (LSD1/KDM1) demethylates histone H3, in addition to the tumor suppressor p53 and DNA methyltransferase 1 (Dnmt1), thus regulating eukaryotic gene expression by altering chromatin structure. Specific inhibitors of LSD1 are desired as anti-cancer agents, since LSD1 aberrations are associated with several cancers, and LSD1 inhibition restores the expression of abnormally silenced genes in cancerous cells. In this study, we designed and synthesized several candidate compounds to inhibit LSD1, based on the structures of LSD1 and monoamine oxidase B (MAO-B), in complex with an anti-depressant tranylcypromine (2-PCPA) derivative. The compound S2101 showed stronger LSD1 inhibition than tranylcypromine and the known small LSD1 inhibitors in LSD1 demethylation assays, with <i>k</i><sub>inact</sub>/<i>K<sub>I</sub></i> values of 4560 M <sup>-1</sup> s <sup>-1</sup>. In comparison with tranylcypromine, the compound displayed weaker inhibition of the monoamine oxidases. The inhibition modes of the two 2-PCPA derivatives, 2-PFPA and S1201, were identified by determining the inhibitor-bound LSD1 structures, which revealed the enhanced stability of the inhibitor-FAD adducts by their interactions with the surrounding LSD1 residues. These molecules are potential pharmaceutical candidates for cancer or latent virus infection, as well as research tools for LSD1-related biological investigations.<i></i><sub></sub><sup></sup>
