About this Resource
Transcription Factor Binding Sites (TRANSFAC) is a knowledge-base containing published data on eukaryotic transcription factors and miRNAs, their experimentally-proven binding sites, and regulated genes. The same data also forms the basis of derived positional weight matrices which can be used with the included Match™ tool to search DNA sequences for putative transcription factor binding sites. Integrated transcription factor ChIP-Seq, DNase hypersensitivity and histone methylated intervals from the ENCODE project complement the curated and predicted binding site data. All data, including the transcription factor – gene interactions, matrix library and command line Match™ program are available for download.
