This study explores the relationship among Sir2, Sum1, and Hst1 proteins within the promoter regions of yeast genes. It delves into their binding at specific locations like inside ORFs or intergenic regions, peak binding sites, and regions near the 3’ end of ORFs. The analysis also considers the distribution of tags associated with Sir2, Sum1, and Hst1, shedding light on their functional roles.
