Chromatin-remodeling protein that binds DNA through histones and regulates gene transcription. May specifically recognize and bind trimethylated 'Lys-27' (H3K27me3) and non-methylated 'Lys-4' of histone H3 (By similarity). Probable chromatin remodeling factor. Belongs to the SNF2/RAD54 helicase family. Truncated N-terminus.
