In the field of molecular biology, the Mi-2/NuRD (Nucleosome Remodeling Deacetylase) complex, is a group of associated proteins with both ATP-dependent chromatin remodeling and histone deacetylase activities.[1][2] As of 2007[update], Mi-2/NuRD was the only known protein complex that couples chromatin remodeling ATPase and chromatin deacetylation enzymatic functions.[3]
