Database Description

ooTFD (1) is a database of transcription factors maintained in object-oriented and object-relational database systems. There are, at the time of this writing, about 7500 TF binding sites entries in this database, from both prokaryotic and eukaryotic sources, as well as roughly 500 TF binding site matrices. A number of tools and services are available for commonly performed sequence analyses against these datasets, as well as for the performing of ooTfd database queries are provided at the IFTI-MIRAGE web site. Matrix entries in this database are given a quality score according to the statistical methodology described by Rahmann et.al. (2), which may be utilized in the interpretation of matrix-based TF binding site searches. Entries in this database resource are linked, either through hard links based on published experimental results, or through precomputed datasets, to entries in EPD (3), PKR (4), and PDB (5). ooTFD and associated utilities can be accessed at http://www.ifti.org/ootfd/ .
