These tracks represent the experimentally validated promoters generated by the Eukaryotic Promoter Database.
Each item in the track is a representation of the promoter sequence identified by EPD. The "thin" part of the element represents the 49 bp upstream of the annotated transcription start site (TSS) whereas the "thick" part represents the TSS plus 10 bp downstream. The relative position of the thick and thin parts define the orientation of the promoter.
Note that the EPD team has created a public track hub containing promoter and supporting annotations for human, mouse, and other vertebrate and model organism genomes.
For a description of the methodology and principles used by EPD to predict TSSs, refer to Dreos et al. (2013) in the References section below. A more detailed description of how this data was generated can be found at the following links:
