This protein contains the WAC_Acf1_DNA_bd (ATP-utilizing chromatin assembly and remodeling) region, as well as the DDT, WHIM1 (WSTF, HB1, Itc1p, and MBD9 motif 1), and WSD (Williams-Beuren syndrome DDT (WSD), D-TOX E motif) domains for histone recognition and DNA binding. Here, DDT is linked to Williams syndrome.
