TRANSFAC® release 2020.3
The TRANSFAC® database on transcription factors, their genomic binding sites and DNA-binding motifs (PWMs), contains these new data features:
- Extended range of species for Match / FMatch upload
Genomic intervals in BED format from the species Drosophila melanogaster, rhesus macaque (Macaca mulatta), and pig (Sus scrofa) can now be uploaded as input for the analysis tools Match, Fmatch, and Composite model search, allowing to search for (overrepresented) transcription factor binding sites or binding site pairs in the promoter sequences of these species.
- Additional files in the TRANSFAC® and associated TRANSPro™ download packages
For TRANSFAC files in JSON format, there is a short guide and example scripts how to import them into a PostgreSQL database and have the advantage to join and query data from separate files.
The TRANSPro package now contains promoter data in Gene Transfer Format (GTF) for the species human, mouse, rat, pig, rhesus macaque, Drosophila melanogaster, and Arabidopsis thaliana.
- Enhanced human SNP content
The 2020 dbSNP release 154 data for human has been integrated and increases the number of SNPs mapped to human promoter sequences by more than 10,000,000 new single nucleotide variations compared to the previously used version 151.
Genomic information for genes, promoters, and ChIP fragments for the species human, mouse, rat, pig, macaque, Drosophila, and Arabidopsis is now based on Ensembl release 100.

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).
