[[http://www.uniprot.org/uniprot/KDM1A_HUMAN 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.<ref>PMID:12032298</ref> <ref>PMID:15620353</ref> <ref>PMID:16079795</ref> <ref>PMID:17805299</ref> <ref>PMID:20228790</ref>

Lysine-specific demethylase 1 (LSD1) is a flavin adenine dinucleotide (FAD)-dependent enzyme that catalyzes the demethylation of histone H3 and regulates gene expression. Because it is implicated in the regulation of diseases such as acute myeloid leukemia, potent LSD1-specific inhibitors have been pursued. Trans -2-phenylcyclopropylamine (2-PCPA)-based inhibitors featuring substitutions on the amino group have emerged, with submicromolar affinities toward LSD1 and high selectivities over monoamine oxidases (MAOs). We synthesized two N -alkylated 2-PCPA-based LSD1 inhibitors, S2116 and S2157, based on the previously developed S2101. S2116 and S2157 exhibited enhanced potency for LSD1 by 2.0- to 2.6-fold, as compared with S2101. In addition, they exhibited improved selectivity over MAOs. Structural analyses of LSD1 co-crystallized with S2101, S2116, S2157, or another N -alkylated inhibitor (FCPA-MPE) confirmed that the N -substituents enhance the potency of a 2-PCPA-based inhibitor of LSD1, without constituting the adduct formed with FAD.
