چکیده انگلیسی
Transcriptional activation of yeast INO1 requires SWI/SNF and INO80 for nucleosome disruption at the promoter. However, the cooperative interplay among remodelers and their recruitment dynamics in activation have thus far been vague. Here, we showed, using chromatin immunoprecipitation, that both SWI/SNF and INO80 are present at the promoter and are restricted to the promoter, indicating that they directly participate in localized INO1 chromatin remodeling. Furthermore, both SWI/SNF and INO80 are absent at the INO1 promoter in ino2Î cells, suggesting that these are activator-dependent remodelers. We have also found that the presence of INO80 is required for SWI/SNF recruitment, indicating that INO80 arrives first at the promoter followed by SWI/SNF. In light of these findings, we proposed a model which describes the order of events in INO1 activation.
