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

Histone demethylase LSD1 regulates transcription by demethylating Lys(4) of histone H3. The crystal structure of the enzyme in complex with CoREST and a substrate-like peptide inhibitor highlights an intricate network of interactions and a folded conformation of the bound peptide. The core of the peptide structure is formed by Arg(2), Gln(5), and Ser(10), which are engaged in specific intramolecular H-bonds. Several charged side chains on the surface of the substrate-binding pocket establish electrostatic interactions with the peptide. The three-dimensional structure predicts that methylated Lys(4) binds in a solvent inaccessible position in front of the flavin cofactor. This geometry is fully consistent with the demethylation reaction being catalyzed through a flavin-mediated oxidation of the substrate amino-methyl group. These features dictate the exquisite substrate specificity of LSD1 and provide a structural framework to explain the fine tuning of its catalytic activity and the active role of CoREST in substrate recognition.
