title: Vitamin D receptor (VDR) promoter targeting through a novel chromatin remodeling complex.
abstract: We have purified nuclear complexes for Vitamin D receptor (VDR), and identified one of them as a novel ATP-dependent chromatine remodeling containing Williams syndrome transcription factor (WSTF), that is supposed to be responsible for Williams syndrome. This complex (WSTF including nucleosome assembly complex (WINAC)) exhibited an ATP-dependent chromatin remodeling activity in vitro. Transient expression assays revealed that WINAC potentiates ligand-induced function of VDR in gene activation and repression. Thus, this study describes a molecular basis of the VDR function on chromosomal DNA through chromatine remodeling.
