Figure 3: The CoREST and NCoR/SMRT complexes. Schematic representation of the CoREST (a) and the NCoR/SMRT (b) complexes. The CoREST complex is included in the CtBP-containing complexes. The empty dotted boxes indicate that both CoREST and NCoR/SMRT complexes lack RbAp46/RbAp48 subunits, which are widely observed in HDAC-containing complexes.
