Transcription regulatory regions database (TRRD): its status in 1999

The Transcription Regulatory Regions Database (TRRD) is a curated database designed for accumulation of experimental data on extended regulatory regio ns of eukaryotic genes, the regulatory elements they contain, i.e., transcr iption factor binding sites, promoters, enhancers, silencers, etc., and exp ression patterns of the genes. Release 4.1 of TRRD offers a number of signi ficant improvements, in particular, a more detailed description of transcri ption factor binding sites, transcription factors per se, and gene expressi on patterns in a computer-readable format. In addition, the new TRRD releas e provides considerably more references to other molecular biological datab ases. TRRD 4.1 is installed under SRS and is available through the WWW at h ttp://www.bionet.nsc.ru/trrd/.
