We use self organizing maps to explore the combinatorial space of transcription factor binding. This method allowed us to explore the full space of 128 transcription factors as well as compare patterns across different cell-types and species.

RegulomeDB is a database that annotates SNPs with known and predicted regulatory elements in the intergenic regions of the H. sapiens genome. Known and predicted regulatory DNA elements include regions of DNAse hypersensitivity, binding sites of transcription factors, and promoter regions that have been biochemically characterized to regulation transcription.
RegulomeDB is available at http://RegulomeDB.org/.

To intuitively summarize and display individual sequence data as an accurate and interpretable signal, we developed F-Seq, a software package that generates a continuous tag sequence density estimation allowing identification of biologically meaningful sites whose output can be displayed directly in the UCSC Genome Browser.
