An improved version of PrESSTo, called SlideBase is now available at http://slidebase.binf.ku.dk
SlideBase offers selection of cell or tissue specific genomic elements using sliders for the following datasets:

Search for promoters by expression or locationShow Details

CAGE tags identify capped RNA 5'ends, which in many cases are associated with TSSs and in extension core promoters. Clusters of nearby CAGE tags can be assessed for expression by counting the number for CAGE tags from the FANTOM5 libraries (The FANTOM 5 Consortium and the RIKEN PMI and CLST (DGT)). This tool allows for selection of promoters with expression constrained over the FANTOM5 libraries. Libraries are arranged in "expression facets" that group similar samples. You can set percentage of expression constraints for primary cells and/or tissues(organs) by moving the sliders below. It is also possible to set location constrains based on the genomic location of promoters. The "How?" buttons give more help. The number of resulting promoters is updated in real time to the right. Clicking on the "See detailed Results" button will direct to a page displaying detailed information about the resulting promoters.
