SMRT and N-CoR function as activating cofactors for HDAC3: recombinant HDAC3 alone is enzymatically inactive, but a deacetylase activating domain (DAD) within one SANT motif of SMRT (and cognate DAD in N-CoR) is necessary and sufficient to activate HDAC3 catalytic activity; DAD mutations that abolish HDAC3 interaction also eliminate HDAC activity and SMRT's major repression function. |

HDAC3 has selective neurotoxic activity: forced expression kills cerebellar granule neurons and cortical neurons but not non-neuronal cells. Neurotoxicity is inhibited by IGF-1/Akt signaling and by GSK3β inhibition. GSK3β directly phosphorylates HDAC3, suggesting neuronal death-promoting action of GSK3β is partly mediated through HDAC3 phosphorylation. |

HDAC3 activity also partially controls nuclear localization of MutSβ via an NLS-overlapping deacetylation region. |
