REDflyis a curated collection of known Drosophila transcriptional cis-regulatory modules (CRMs) and transcription factor binding sites (TFBSs). Despite more than 20 years of experimental determination of these elements, the data have never been collected into a single searchable database. REDfly seeks to include all experimentally verified fly regulatory elements along with their DNA sequence, their associated genes, and the expression patterns they direct. Expression patterns are annotated using a defined anatomy ontology to enable high interoperability with FlyBase, FlyExpress, the BDGP in situ hybridization database, and other model organism resources.

If you know of experimentally verified cis-regulatory elements that are not included in the REDfly database, or have corrections to the archived data, please contact us.

REDfly has 738 CRMs associated with 249 genes, and 1342 TFBSs bound by 83 transcription factors acting on 97 target genes. These data are based on 401 curated publications.
