DeFCoM: analysis and modeling of transcription factor binding sites using a motif-centric genomic footprinter

Bryan Quach, Terrence S. Furey
2016 Bioinformatics  
Results: Using DNase-seq data from the ENCODE project, we show that a large degree of previously uncharacterized site-to-site variability exists in footprint signal across motif sites for a transcription  ...  Motivation: Identifying the locations of transcription factor binding sites is critical for understanding how gene transcription is regulated across different cell types and conditions.  ...  We also thank Tatsunori Hashimoto for his support in updating PIQ for compatibility with our motif site evaluation sets.  ...
