TRANSFAC is a database on eukaryotic transcription factors and their=20
binding sites. As new features, it now includes the complete amino acid=20
sequences of the transcription factors (FACTOR table) and links to the=20
Eukaryotic Promoter Database (EPD) in its SITE table. Moreover, the data=20
volume has increased comprising now 2080 FACTOR and 4362 SITE entries.

As a new search option, you may retrieve factors by their molecular=20
weight.
Moreover, you will find a SRS5 version which offers additional retrieval=20
options for the TRANSFAC tables, for EMBL, SwissProt, PIR, =85 (for this,=

we give credit to Thure Etzold, EBI, Hinxton).

As for release 3.0, there are also extensive links with TRRD=20
(Transcription Regulatory Regio Database) and COMPEL (Composite Elements=20
Database), maintained at the Institute of Cytology and Genetics (ICG,=20
Novosibirsk, Russia: N. A. Kolchanov/A. Kel et al.).

The sequence information contained in the SITE table is used by=20
PatternSearch 1.0 for interactive sequence scanning for potential TF=20
binding sites.

An updated library of matrices for transcription factor binding sites=20
will be provided very soon which can be used for sequence analysis with=20
MatInspector release 2.0 (Quandt et al., 1995, Nucleic Acids Res.=20
23:4878-4884).=20
