CoREST is an integral component of a distinct HDAC1/2-containing complex (CoREST-HDAC complex) that lacks RbAp46/48. The HDAC1/2-interacting region of CoREST maps to a 179-aa region containing a SANT domain, and corepressor function of CoREST depends on this region. ZNF217 (not REST) was identified as an interacting partner in this complex. |

CoREST is essential for LSD1 (BHC110)-mediated demethylation of H3K4 on nucleosomal substrates. Recombinant LSD1 alone cannot demethylate nucleosomes, but LSD1-containing complexes with CoREST can; CoREST enhances LSD1-nucleosome association. Depletion of CoREST in vivo leads to de-repression of REST target genes and increased H3K4 methylation. |
