Abstract
Three databases that provide data on transcriptional regulation are described. TRANSFAC is
a database on transcription factors and their DNA binding sites. TRRD (Transcription
Regulatory Region Database) collects information about complete regulatory regions, their
regulation properties and architecture. COMPEL comprises specific information on
composite regulatory elements. Here, we describe the present status of these databases and
the first steps towards their federation.
