PRE Mapper |
PRE Mapper is a bioinformatic tool written in Perl for searching Polycomb Response Elements (PREs) in Drosophila.
This tool's algorithm uses motif of PRE binding proteins and looks for motif clusters and patterns to define a PRE.
The motifs used in this tool include Pho, GAF, Dsp1, Sp1, Zeste, Grh, Adf1 and Cg. For additional information about these motifs and binding proteins,

PRE motif clusters & conditions for PRE search |
- Pho-distinct cluster (Pho, GAF, DSP1, Zeste, Sp1 motifs) & Total Motifs 10 & Average Gap 60.
- Pho-generic cluster (Pho + four other motifs) & Total Motifs 16 & Average Gap 40.
- Cg or Pho-independent cluster (two Cg motifs + four other motifs)& Total Motifs 16 & Average Gap 40.

Any given PRE may possess at least one of the above clusters on it.
