Recent advances in understanding chromatin remodeling by Swi/Snf complexes.

Members of the Swi/Snf family of chromatin-remodeling complexes play critical roles in transcriptional control. Recent studies have made significant advances in our understanding of the fundamental aspects of Swi/Snf complexes, including the roles of specific subunits, the repression of transcription, and the mechanism of remodeling. In addition, new findings also indicate an important role for the Swi/Snf-related complex, RSC, in controlling gene expression.
