Gong F, et al. (2006) Rad4-Rad23 interaction with SWI/SNF links ATP-dependent chromatin remodeling with nucleotide excision repair. Nat Struct Mol Biol 13(10):902-7
Abstract: Chromatin rearrangement occurs during nucleotide excision repair (NER). Here we show that Snf6 and Snf5, two subunits of the SWI/SNF chromatin-remodeling complex in Saccharomyces cerevisiae, copurify with the NER damage-recognition heterodimer Rad4-Rad23. This interaction between SWI/SNF and Rad4-Rad23 is stimulated by UV irradiation. We demonstrate that NER in the transcriptionally silent, nucleosome-loaded HML locus is reduced in yeast cells lacking functional SWI/SNF. In addition, using a restriction enzyme accessibility assay, we observed UV-induced nucleosome rearrangement at the silent HML locus. Notably, this rearrangement is markedly attenuated when SWI/SNF is inactivated. These results indicate that the SWI/SNF chromatin-remodeling complex is recruited to DNA lesions by damage-recognition proteins to increase DNA accessibility for NER in chromatin.
