Collects promoter features in Saccharomyces cerevisiae. YPA integrates resources such as transcription start sites (TSSs], TATA boxes, transcription factor binding sites (TFBS], nucleosome occupancy, DNA bendability, transcription factor (TF)-TF interaction, and gene expression data. The database provides an interface for browsing the yeast genome and viewing multiple promoter features simultaneously. Users can retrieve the data collected from various sources.
