摘要: Eukaryotic gene expression is often tightly regulated by interactions between transcription factors (TFs) and their DNA cis targets. Yeast one-hybrid (Y1H) one of the most extensively used methods to discover these interactions. We developed a high-throughput meiosis-directed yeast system using Magic Markers synthetic genetic array analysis. The has factor-DNA interaction discovery rate twice as high conventional diploid-mating approach processing time nearly one-tenth haploid-transformation method. also offers highest accuracy in identifying TF-DNA that can be authenticated vivo chromatin immunoprecipitation. With unique features, this Y1H particularly suited for constructing novel comprehensive genome-scale regulatory networks various organisms.
