The ModERN Resource: Genome-Wide Binding Profiles for Hundreds of and Transcription Factors.

To develop a catalog of regulatory sites in two major model organisms, and , the modERN (model organism Encyclopedia of Regulatory Networks) consortium has systematically assayed the binding sites of transcription factors (TFs). Combined with data produced by our predecessor, modENCODE (Model Organism ENCyclopedia Of DNA Elements), we now have data for 262 TFs identifying 1.23 M sites in the fly genome and 217 TFs identifying 0.
