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] [RCOR3_HUMAN] May act as a component of a corepressor complex that represses transcription (Potential).

Publication Abstract from PubMed

Mammalian genomes harbor three CoREST genes. rcor1 encodes CoREST (CoREST1) and the paralogues rcor2 and rcor3 encode CoREST2 and CoREST3, respectively. Here, we describe specific properties of transcriptional complexes formed by CoREST proteins with the histone demethylase LSD1/KDM1A and histone deacetylases HDAC1/2 and the finding that all three CoRESTs express in the adult rat brain. CoRESTs interact equally strong with LSD1/KDM1A. Structural analysis shows that the overall conformation of CoREST3 is similar to that of CoREST1 complexed with LSD1/KDM1A. Nonetheless, transcriptional repressive capacity of CoREST3 is lower than that of CoREST1, which correlates with the observation that CoREST3 leads to a reduced LSD1/KDM1A catalytic efficiency. Also, CoREST2 shows a lower transcriptional repression than CoREST1, which is resistant to HDAC inhibitors. CoREST2 displays lower interaction with HDAC1/2 which is barely present in LSD1/KDM1A-CoREST2 complexes. A non-conserved Leucine in the first SANT domain of CoREST2 severely weakens its association to HDAC1/2. Furthermore, CoREST2 mutants with either increased or lacking HDAC1/2 interaction feature equivalent transcriptional repression capacities, indicating that CoREST2 represses in a HDAC-independent manner. In conclusion, differences among CoREST proteins are instrumental to the modulation of protein-protein interactions and catalytic activities of LSD1/KDM1A-CoREST-HDAC complexes, fine tuning gene expression regulation.
