The current matrix library (Matrix Family Library Version 8.2) contains 1166 weight matrices in six groups (transcription factor binding sites from species fungi, insects, plants, vertebrates, and miscellaneous as well as general core promoter elements).
| Group | # matrices | # matrix families | # IUPACs | # IUPAC families |
|---|---|---|---|---|
| Fungi | 149 | 67 | --- | --- |
| Insects | 88 | 50 | --- | --- |
| Plants | 165 | 72 | 431 | 323 |
| Vertebrates | 727 | 170 | --- | --- |
| Miscellaneous | 21 | 17 | --- | --- |
| General Core Promoter Elements | 16 | 10 | --- | --- |
| Total | 1166 | 386 | 431 | 323 |
The vertebrate group represents binding site descriptions of 5747 transcription factors. The plant group represents binding site descriptions of 927 transcription factors from several plant species. The fungi group represents binding site descriptions of 140 transcription factors from Saccharomyces cerevisiae and Schizosaccharomyces pombe.
For plants, a IUPAC library containing individual plant transcription factor binding sites is available in addition to the matrix library. The IUPAC library is based on PLACE). Identical and similar TF binding sites of PLACE have been grouped into IUPAC families and very unspecific binding sites (e.g. CANNTG) have been removed.
