If you are looking for target genes of your favourite transcription factor you are at the right place. Current methods are mainly based on sequence information alone. This classic way will produce a huge amount of false positives.[Wasserman WW and Sandelin A (2004) Applied bioinformatics for the identification of regulatory elements. Nat. Rev. Genet., 5, 276-287]. In order to get predictions that are much more likely to produce true positve results in your experimental work we provide a web tool that is based on large scale functional data as well as optionally based on binding statistics that will give you preselected candidates. Behind this functional data there are more than 1200 microarray experiments. So you can start your experimental work on genes that are more likey to be true targets because they are functionally very similar to your input set. That will save work and time.
