Promoters research
- Found free promoters database at the Eukaryotic Promoter Database website
- Retrieved BED file of all human promoters from: http://epd.vital-it.ch/get_promoters.php
- Selected H. sapiens, left all other options blank, clicked [select], downloaded BED file, uploaded to Galaxy as Promoters EPD All
- Total promoters: 23,316
- Each is only 10 bp long
- Gene names are included!
- Note: Custom-generated promoter file (500 bp TSS regions) = 26,960. This is over 3k more than the EPD.
New Galaxy files
Note: EPD allows selection of promoter sub-classes
- All EPD promoters - uploaded as Promoters EPD All
