摘要: Regulation of gene expression requires dynamic changes in chromatin, but the nature these is not well understood. Here, we show that progesterone treatment cultured cells leads to recruitment receptor (PR) and SWI/SNF-related complexes Mouse Mammary Tumor Virus (MMTV) promoter, accompanied by displacement histones H2A H2B from nucleosome containing binding sites, adjacent nucleosomes. PR recruits SWI/SNF MMTV nucleosomes vitro facilitates synergistic receptors nuclear factor 1 promoter. In assembled on or mouse rDNA promoter sequences, catalyzes ATP-dependent sliding histone octamer followed only H2B. arrays, displaces B nucleosome. Thus, outcome remodeling depends DNA sequence.
