Function
[SWI1_YEAST] Involved in transcriptional activation. Component of the SWI/SNF complex, an ATP-dependent chromatin remodeling complex, which is required for the positive and negative regulation of gene expression of a large number of genes. It changes chromatin structure by altering DNA-histone contacts within a nucleosome, leading eventually to a change in nucleosome position, thus facilitating or repressing binding of gene-specific transcription factors.
Publication Abstract from PubMed
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 NMR spectroscopy. Yeast SWI1 ARID domain is composed of seven alpha-helices,6 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 homologous, the yeast SWI1 ARID domain binds DNA non-specifically. Proteins 2012. (c) 2012 Wiley-Liss, Inc.
