DBNAME DRSC BASEURL http://www.flyrnai.org/cgi-bin/RNAi_gene_lookup_public.pl?gname= HOMEURL http://www.flyrnai.org/ DESC RNA interference (RNAi) has become a powerful tool for genetic screening in Drosophila. At the Drosophila RNAi Screening Center (DRSC), we are using a library of over 21,000 double-stranded RNAs targeting known and predicted genes in Drosophila. The DRSC database stores fly gene annotations, RNAi reagent information as well as RNAi screen data that were generated at DRSC. The long-term goal of this database is to provide annotations for as many of the uncharacterized genes in Drosophila as possible. Data from published screens are available to the public through a highly configurable interface that allows detailed examination of the data and provides access to a number of other databases and bioinformatics tools.
