Differential properties of transcriptional complexes formed by the CoREST family.

ABSTRACT: 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 1 and 2 (HDAC1/2) and the finding that all three CoRESTs are expressed in the adult rat brain. CoRESTs interact equally strongly 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 lo
