Clusters of microRNAs and Their Number of Predicted Target Genes

Clusters of unique microRNAs, conserved in all flies, with precursor sequences, originating from a genomic region of less than 50 kB. The number of unique genes with at least two anchor sites for different microRNAs of a given cluster is indicated. Predictions are computed for both set 1 and set 2, and for anchors conserved in the melanogaster and obscura groups, and in all seven fly species. If clustered microRNA precursors reside in an intron of an annotated FlyBase gene, the identifier is also indicated.
