Abstract


SWI1 is a subunit of the SWI/SNF complex involved in chromatin remodeling. It contains an AT-rich interaction domain (ARID) which has the potential DNA binding activity. In this study, we determined the solution structure of the SWI1 ARID domain from Saccharomyces cerevisiae by nuclear magnetic resonance spectroscopy. Yeast SWI1 ARID domain is composed of seven alpha helices, six of which are conserved among the ARID family. In addition, the DNA-binding activity of the SWI1 ARID domain was confirmed by chemical shift perturbation assay. Similar to its human homolog, the yeast SWI1 ARID domain binds DNA nonspecifically.
