If you have a gene group (e.g. from gene expression studies) and you are interested whether there are any transcription factor binding sites enriched in the promoters of your gene group, this site may help you.
The prediction of which transcription factors regulate a group of target genes is based on affinities of the transcription factors to the putative promotors of the genes. The affinities have been precalculated based on the available positional frequency matrices for the transcription factors .
If you use our method, please cite , where we provide details on TransFind implementation and its evaluation.
Select "Start prediction" in the main menu to submit your gene group (and, if you wish, a background gene group). Select "About TransFind" if you want to learn more about the algorithms used.
