TRANSFAC download

TRANSFAC download

The TRANSFAC® flat file download (including the databases TRANSCompel® and TANSProTM) contains eukaryotic transcription factors (and miRNAs), their experimentally determined genomic binding sites and consensus DNA-binding motifs (PWMs), as well as data on combinatorial gene regulation and factor-factor interaction. Promoters, enhancers and silencers annotated with transcription  factor  ChIP-Seq,  DNase hyper-

sensitivity and histone methylated intervals from the ENCODE project and from other sources complement the manually curated binding site data. Based on the positional weight matrices (PWMs) transcription factor binding sites can be predicted in regulatory regions. In the TRANSFAC® flat file download, the tools of the MatchTM Library can be used on command line or the PWMs can be used with tools of the user.

Structure

Structure of the TRANSFAC® flat file download release is as follows:

TRANSFAC download structure

At the center of TRANSFAC® are transcription factors and their DNA binding sites based on experimental evidence extracted from scientific publications. The interlinked factor and site entries are captured in the respective flat files. Interactions between two or more factors are also included. TF-binding sites can be with or without a connection to a gene. Genomic sites are mapped to promoter sequences in the TRANSProTM module of TRANSFAC®. Besides linkage of factors via binding sites to regulated genes, monomeric factors are also linked to their encoding genes. In some cases this may also lead to autoregulatory loops, where a factor regulates the expression of its own gene. Based on gene-factor and (indirect) factor-gene links, gene-regulatory networks can be extracted.

The transcription factor classification from TFClass has been integrated. Based on the collection of DNA-binding sites for a transcription factor, consensus binding motifs in form of positional weight matrices (PWMs) are derived, which can be used by the command line tools in the Match Library for transcription factor binding site prediction in regulatory DNA sequences. Synergistic and antagonistic interactions between transcription factors binding to closely situated sites, so called composite regulatory elements, are included in the COMPEL flat file of the TRANSCompel® module of TRANSFAC®. ChIP-seq and other high-throughput data are also included and are mapped to promoter and enhancer regions.

Transcription Factor Classification

Most transcription factors (TFs) possess a DNA-binding domain (DBD), which mediates the recognition of specific, short DNA sequence elements in promoter, enhancer, etc. In order to approach the problem of deciphering the underlying DNA-protein recognition code, we have completely revised an earlier TF classification scheme (1,2) by adapting it to the wealth of data that were reported during the last ten years (TFClass; 3-5). TFClass has been implemented at the Dept. of Bioinformatics at the University Medical Center Göttingen (3,6).
Part of this work was done in the context of the Syscol project, where our partner at the Karolinska institute (Prof. J. Taipale and his team) have characterized the DNA-binding profiles of more than 400 mammalian TFs (7). It will be tempting to compare the similarities of their matrices with the DBD classification reported here, and with our own approaches to classify DNA-binding profiles (8).
