YeasTSS: An Integrative Web Database of Yeast Transcription Start Sites

BioRxiv : the Preprint Server for Biology
Jonathan McMillanZhenguo Lin


The transcription initiation landscape of eukaryotic genes is complex and highly dynamic. In eukaryotes, genes can generate multiple transcript variants that differ in 5' boundaries due to usages of alternative transcription start sites (TSSs), and the abundance of transcript isoforms are highly variable. Due to a large number and complexity of the TSSs, it is not feasible to depict details of transcript initiation landscape of all genes using text-format genome annotation files. Therefore, it is necessary to provide data visualization of TSSs to represent quantitative TSS maps and the core promoters. In addition, the selection and activity of TSSs are influenced by various factors, such as transcription factors, chromatin remodeling, and histone modifications. Thus, integration and visualization of functional genomic data related to these features could provide a better understanding of the gene promoter architecture and regulatory mechanism of transcription initiation. Yeast species play important roles for the research and human society, yet no database provides visualization and integration of functional genomic data in yeast. Here, we generated quantitative TSS maps for twelve important yeast species, inferred their core p...Continue Reading
